CVE-2026-196358.8 HIG—
——0A local privilege escalation vulnerability exists in Security Center. An attacker with write access to a specific configuration file could achieve arbitrary code execution with elevated privileges, without requiring further user or victim interaction.17hCVE-2026-196365.3 MED—
——0An issue was identified in which CSRF tokens were generated using a predictable method, potentially reducing their effectiveness as a security control. This has been addressed by improving the randomness and entropy of token generation.1dCVE-2026-198478.8 HIG—
——0A security flaw has been discovered in TOTOLINK A800R 4.1.2cu.5137_B20200730. Affected is the function setWiFiWpsConfig of the file /cgi-bin/cstecgi.cgi of the component wps.so. The manipulation of the argument pin results in stack-based buffer overflow. The attack can be launched remotely. The exploit has been released to the public and may be used for attacks.1dCVE-2026-123648.4 HIG—
——0The user-space system-call verifier z_vrfy_z_log_msg_static_create() in subsys/logging/log_msg.c was a pure pass-through: it forwarded the caller-supplied source, desc, package, and data arguments directly to the kernel-mode implementation z_impl_z_log_msg_static_create() without performing any of the mandatory K_SYSCALL_* checks. Because z_log_msg_static_create() is declared __syscall, under CONFIG_USERSPACE any unprivileged user-mode thread can invoke it directly with fully attacker-controlled arguments.
The kernel-mode handler dereferences each of these untrusted values: frontend_runtime_filtering() reads through the source pointer as a struct log_source_dynamic_data, cbprintf_package_copy() reads desc.package_len bytes from the package pointer, and z_log_msg_finalize() performs a memcpy() of desc.data_len bytes from the data pointer. With no verification, a user thread can supply arbitrary kernel addresses and arbitrary lengths, and the kernel will read from them.
The impact is a kernel-mode denial of service (the kernel faults dereferencing an attacker-chosen pointer) and, where a log backend output is observable to the attacker, disclosure of arbitrary kernel memory copied into the emitted log message — a confidentiality breach across the user/kernel boundary that the userspace sandbox is meant to enforce. The reads do not corrupt kernel memory, so there is no out-of-bounds write primitive.
The fix adds the required validation to the verifier: it bounds desc.package_len against Z_LOG_MSG_MAX_PACKAGE, rejects non-NULL/length mismatches, and applies K_SYSCALL_MEMORY_READ() to package, data, and (when runtime filtering with a frontend is enabled) source, so any out-of-bounds or kernel pointer now raises K_OOPS instead of being honored.1dCVE-2026-33181——

——0Grav API plugin versions before 1.0.13 fail to enforce API key scope caps in ConfigController super-scope gates, allowing scoped keys to write scheduler configuration. Attackers with a scoped api.config.write key can inject arbitrary commands into scheduler.custom_jobs that execute via Symfony Process for remote code execution.1dCVE-2026-72239——
——0In the Linux kernel, the following vulnerability has been resolved:
x86/virt/sev: Revert "Drop WBINVD before setting MSR_AMD64_SYSCFG_SNP_EN"
Revert
99cf1fb58e68 ("x86/virt/sev: Drop WBINVD before setting MSR_AMD64_SYSCFG_SNP_EN").
Section 8.8 of the SNP spec says:
Before invoking SNP_INIT_EX with INIT_RMP set to 1, software must ensure
that no CPUs contain dirty cache lines for the memory containing the RMP.
Cachelines can be moved from cache to cache in a dirty state. The
wbinvd_on_all_cpus() before SNP_INIT_EX flushes the caches for each CPU, but
if the IPIs for WBINVD race with this dirty cacheline movement, it is possible
that they may not get flushed, violating the firmware requirement.
Doing wbinvd_on_all_cpus() before setting SNPEn is safer since the RMP
table is not yet in use.

——0In the Linux kernel, the following vulnerability has been resolved:
mm/damon/sysfs-schemes: fix dir put orders in access_pattern_add_dirs()
Patch series "mm/damon/sysfs-schemes: fix wrong directories put orders in
error paths".
Error paths of damon_sysfs_access_pattern_add_dirs() and
damon_sysfs_scheme_add_dirs() functions put references to directories in
wrong orders. As a result, uninitialized memory dereference and/or
memory leak can happen. Fix those.
This patch (of 2):
In access_pattern_add_dirs(), error handling path puts references starting
from setup failed directories. If the failure happpened from the initial
allication in the setup functions, uninitialized memory dereference
happen. The allocation failures will not commonly happen, but the
consequence is quite bad. Fix the wrong reference put orders.
The issue was discovered [1] by Sashiko.15hCVE-2026-72179——
——0In the Linux kernel, the following vulnerability has been resolved:
riscv: cacheinfo: Fix node reference leak in populate_cache_leaves
Currently, the while loop drops the reference to prev in each iteration.
If the loop terminates early due to a break, the final of_node_put(np)
correctly drops the reference to the current node.
However, if the loop terminates naturally because np == NULL, calling
of_node_put(np) is a no-op. This leaves the last valid node stored in
prev without its reference dropped, resulting in a node reference leak.
Fix this by changing the final `of_node_put(np)` to `of_node_put(prev)`.15hCVE-2026-196394.3 MED—
——0An improper access control vulnerability exists where an authenticated non-administrative application user could potentially view settings outside of their assigned scope.1dCVE-2026-72323——
——0In the Linux kernel, the following vulnerability has been resolved:
ipv4: igmp: Fix potential UAF in igmp_gq_start_timer()
A race condition exists between device teardown (inetdev_destroy) and
incoming IGMP query processing (igmp_rcv), leading to a Use-After-Free
in the IGMP timer callback.
During device destruction, inetdev_destroy() drops the primary reference
to in_device, which can drop its refcount to 0. The actual freeing of
in_device memory is deferred via RCU (using call_rcu()).
Concurrently, igmp_rcv() runs under RCU read lock and obtains the
in_device pointer. Because the memory is RCU-protected, CPU-0 can safely
dereference in_device even if its refcount has hit 0.
However, if CPU-0 calls igmp_gq_start_timer() and re-arms the timer, it
attempts to acquire a reference using in_dev_hold(). This increments the
refcount from 0 to 1, triggering a "refcount_t: addition on 0" warning.
Since the in_device memory is still scheduled to be freed after the RCU
grace period (as the free callback does not check the refcount again),
the device is freed while the timer is still armed. When the timer
expires, it accesses the freed memory, causing a kernel panic.
Fix this by using refcount_inc_not_zero() (via a new helper
in_dev_hold_safe()) to prevent acquiring a reference if the device is
already being destroyed. If the refcount is 0, we do not arm the timer.
A similar issue in IPv6 MLD is fixed in a subsequent patch.15hCVE-2026-72324——
——0In the Linux kernel, the following vulnerability has been resolved:
gpio: mvebu: free generic chips on unbind
irq_alloc_domain_generic_chips() allocates generic chip data that must
be freed via irq_domain_remove_generic_chips(). The devres action
mvebu_gpio_remove_irq_domain() only called irq_domain_remove(), which
only frees the generic chips if IRQ_DOMAIN_FLAG_DESTROY_GC is set.
Call irq_domain_remove_generic_chips() explicitly before
irq_domain_remove() instead.15hCVE-2026-72325——
——0In the Linux kernel, the following vulnerability has been resolved:
perf/x86/amd/core: Avoid enabling BRS from the SVM reload path
Branch Sampling (BRS) and Last Branch Record (LBR) are mutually
exclusive hardware features, and users of both are tracked via
cpuc->lbr_users.
When SVM is toggled on a CPU, the host perf events are reprogrammed to
update the HostOnly filter bit (set when virtualization is enabled,
cleared when it is disabled). On PerfMonV2-capable processors, this
reprogramming is performed by calling amd_pmu_enable_all() to rewrite
the event selectors. However, amd_pmu_enable_all() also calls
amd_brs_enable_all(), which enables BRS whenever cpuc->lbr_users > 0.
Having active LBR events satisfies this gating on processors that have
LBR but not BRS. The kernel then tries to set the BRS enable bit in
DebugExtnCfg (MSR 0xc000010f). Since that bit is deprecated on such
hardware, the write results in a #GP:

x86/boot: Validate console=uart8250 baud rate to fix early boot hang
When the baud rate is empty, 0, invalid, or overflows to 0 when stored
as an int, the system will hang during early boot because of a division
by zero in early_serial_init().
Fall back to DEFAULT_BAUD when the resulting baud rate is 0 to prevent
an early system hang.15hCVE-2026-196798.8 HIG—

——0An authenticated command injection vulnerability exists in Security Center related to file upload processing. An attacker could exploit this issue by uploading a specially crafted file, potentially resulting in arbitrary command execution on the underlying operating system.17hCVE-2026-198228.8 HIG—
——0A vulnerability was identified in Tenda W20E 15.11.0.6(1068_1546_841)_CN_TDC. This issue affects the function lstAdd of the file /goform/editQos of the component QoS Edit. Such manipulation of the argument qosListConnecttedNum leads to stack-based buffer overflow. The attack may be launched remotely. The exploit is publicly available and might be used.1dCVE-2026-72180——
——0In the Linux kernel, the following vulnerability has been resolved:
mm/huge_memory: preserve pmd_swp_uffd_wp on device-private PMD downgrade
change_non_present_huge_pmd() rewrites a writable device-private PMD swap
entry into a readable one without carrying pmd_swp_uffd_wp() across. The
PTE-level change_softleaf_pte() does this correctly; mirror that here,
matching what copy_huge_pmd() does for the fork path. Without the carry,
a plain mprotect() over a UFFD_WP-marked device-private THP strips the bit
and the trap is bypassed on swap-in.15hCVE-2026-72327——
——0In the Linux kernel, the following vulnerability has been resolved:
drm/v3d: Reject invalid indirect BO handle in indirect CSD setup
v3d_get_cpu_indirect_csd_params() looks up the indirect buffer object
from a userspace-supplied handle but never checks the result. A bogus
or stale handle makes drm_gem_object_lookup() return NULL, which is
then stored in info->indirect and only dereferenced later when the
indirect CSD job runs, turning a userspace mistake into a NULL pointer
dereference in the kernel.
Bail out with -ENOENT as soon as the lookup fails, so the bad handle is
rejected at submission time.15hCVE-2026-72329——
——0In the Linux kernel, the following vulnerability has been resolved:
net/liquidio: drop cached VF pci_dev LUT
The PF SR-IOV enable path caches VF pci_dev pointers in
dpiring_to_vfpcidev_lut[] by iterating with pci_get_device(). Those
entries do not own a reference, because the iterator drops the previous
device reference on each step. The cached pointer is then dereferenced
later when handling OCTEON_VF_FLR_REQUEST.
Replace the cached VF mapping with runtime lookup on the mailbox DPI
ring: derive the VF index from q_no, resolve the VF via exported PCI
IOV helpers, validate it with the PF pointer and VF ID, then issue
pcie_flr() and drop the reference with pci_dev_put(). Remove the
unused VF lookup table initialization and cleanup.15hCVE-2026-72330——
——0In the Linux kernel, the following vulnerability has been resolved:
net/tls: Consume empty data records in tls_sw_read_sock()
A peer may send a zero-length TLS application_data record; TLS 1.3
explicitly permits these as a traffic-analysis countermeasure (RFC
8446, Section 5.1). After decryption such a record has full_len ==
0. tls_sw_read_sock() hands it to the read_actor, which has no
payload to consume and returns zero. The loop treats a zero return
as backpressure (used <= 0), requeues the skb at the head of
rx_list, and stops. rx_list is serviced head-first on the next
call, so the empty record is dequeued, fails the same way, and is
requeued again; every later record on the connection is blocked
behind it.
tls_sw_recvmsg() does not stall on this: a zero-length data record
copies nothing and falls through to consume_skb(). Mirror that in
the read_sock() path by recognizing an empty data record before
the actor runs, consuming it, and continuing.15hCVE-2026-72033——
——0In the Linux kernel, the following vulnerability has been resolved:
orangefs: keep the readdir entry size 64-bit in fill_from_part()
fill_from_part() computes the size of a directory entry in size_t but
stores it in a __u32. An entry length near U32_MAX wraps it to a small
value, bypasses the bounds check, and is then used to index the entry,
reading far past the directory part -- an out-of-bounds read that oopses
the kernel.
Compute the size as a u64 so it cannot truncate; the bounds check then
rejects the entry. The trailer is supplied by the userspace client.15hCVE-2026-72155——
——0In the Linux kernel, the following vulnerability has been resolved:
mtd: spi-nor: swp: Improve locking user experience
In the case of the first block being locked (or the few first blocks),
if the user want to fully unlock the device it has two possibilities:
- either it asks to unlock the entire device, and this works;
- or it asks to unlock just the block(s) that are currently locked,
which fails.
It fails because the conditions "can_be_top" and "can_be_bottom" are
true. Indeed, in this case, we unlock everything, so the TB bit does not
matter. However in the current implementation, use_top would be true (as
this is the favourite option) and lock_len, which in practice should be
reduced down to 0, is set to "nor->params->size - (ofs + len)" which is
a positive number. This is wrong.
An easy way is to simply add an extra condition. In the unlock() path,
if we can achieve the same result from both sides, it means we unlock
everything and lock_len must simply be 0. A comment is added to clarify
that logic.15hCVE-2026-72259——
——0In the Linux kernel, the following vulnerability has been resolved:
ASoC: mediatek: mt8192: Release reserved memory on cleanup
The MT8192 AFE probe calls of_reserved_mem_device_init() and falls
back to preallocated buffers when no reserved memory region is
available. When the reserved memory assignment succeeds, however, the
driver never releases it.
Register a devm cleanup action after a successful reserved-memory
assignment so the assignment is released on probe failure and driver
unbind.15hCVE-2026-728108.6 HIG—
——0SiYuan versions before v3.7.4 contain a publish-boundary bypass vulnerability in WebSocket broadcast sessions that allows anonymous readers to receive unfiltered edits. Attackers can establish a WebSocket connection to the publish surface and passively receive real-time content events including password-protected and forbidden documents without authentication.1dCVE-2026-72154——
——0In the Linux kernel, the following vulnerability has been resolved:
openrisc: Fix jump_label smp syncing
The original commit 8c30b0018f9d ("openrisc: Add jump label support")
copies from arm64 and does not properly consider how icache invalidation
on remote cores works in OpenRISC. On OpenRISC remote icaches need to
be invalidated otherwise static key's may remain state after updating.
Fix SMP cache syncing by:
1. Properly invalidate remote core icaches on SMP systems by using
icache_all_inv. The old code uses kick_all_cpus_sync() which runs a
no-op IPI function call on remote CPU's which does execute a lot of
code and flushes many cache lines in the process, but does not flush
all and it's not correct on OpenRISC.
2. For architectures that do not have WRITETHROUGH caches be sure
to flush the dcache after patching.
To test this I first reproduced the issue using a custom test module
[0]. The test confirmed that some icache lines maintained stale
static_key code sequences after calling static_branch_enable(). After
this patch there are no longer jump_label coherency issues.

accel/amdxdna: Fix VMA access race
aie2_populate_range() and amdxdna_umap_release() access a saved VMA
pointer that may have already been freed, leading to a potential
use-after-free.
Remove the VMA accesses from these functions to avoid the race.15hCVE-2026-72332——
——0In the Linux kernel, the following vulnerability has been resolved:
accel/amdxdna: Prevent PM resume deadlock in hwctx_sync_debug_bo()
amdxdna_hwctx_sync_debug_bo() invokes the hardware hwctx_sync_debug_bo()
callback while holding xdna->dev_lock.
The callback may call amdxdna_cmd_submit(), which in turn calls
amdxdna_pm_resume_get(). If the device is suspended,
amdxdna_pm_resume_get() may synchronously execute amdxdna_pm_resume(),
which also acquires xdna->dev_lock, resulting in a deadlock.
Avoid the deadlock by calling amdxdna_pm_resume_get() before holding
xdna->dev_lock in both amdxdna_hwctx_sync_debug_bo() and
amdxdna_drm_config_hwctx_ioctl()15hCVE-2026-72153——
——0In the Linux kernel, the following vulnerability has been resolved:
irqchip/crossbar: Use correct index in crossbar_domain_free()
crossbar_domain_free() resets the domain data and then uses the nulled
out irq_data->hwirq member as index to reset the irq_map[] entry and to
write the relevant crossbar register with a safe entry. That means it
never frees the correct index and keeps the crossbar register connection
to the source interrupt active.
If it would not reset the domain data, then this would be even worse as
irq_data->hwirq holds the source interrupt number, but both the map and
register index need the corresponding GIC SPI number and not the source
interrupt number. This might even result in an out of bounds access as
the source interrupt number can be higher than the maximal index space.
Fix this by using the GIC SPI index from the parent domain's irq_data.15hCVE-2026-72032——
——0In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: HWS, fix matcher leak on resize target setup failure
hws_bwc_matcher_move() allocates a replacement matcher before setting it
as the resize target. If mlx5hws_matcher_resize_set_target() fails, the
replacement matcher is not attached anywhere and is leaked.
Fix the leak by destroying the replacement matcher before returning from
the resize-target failure path.
The bug was first flagged by an experimental analysis tool we are
developing for kernel memory-management bugs while analyzing
v6.13-rc1. The tool is still under development and is not yet publicly
available. Manual inspection confirms that the bug is still
present in v7.1.1.
An x86_64 allyesconfig build showed no new warnings. As we do not have a
mlx5 HWS-capable device to test with, no runtime testing was able to be
performed.15hCVE-2026-728287.2 HIG—
——0Grav Plugin API (getgrav/grav-plugin-api) before 1.0.13 fails to enforce API-key scope caps in InvitationsController. The strip-super and accept-groups decisions are gated on a bare isSuperAdmin() check rather than a scope-aware permission check, so a least-privilege API key (scoped to api.users.write) minted on a super account can create an invitation record containing super-admin access flags. When the invitation is accepted, those flags are written verbatim to the new account, resulting in privilege escalation to a fully controlled super account.1dCVE-2026-72077——

perf/x86/amd/brs: Fix kernel address leakage
A user-only branch stack can contain branches that originate from
the kernel. As a result, kernel addresses are exposed to user space
even when PERF_SAMPLE_BRANCH_USER is requested. On AMD processors
supporting X86_FEATURE_BRS (Zen 3 only), perf can still report entries
such as SYSRET/interrupt returns for which the branch-from addresses
are in the kernel.
E.g.

BRS provides no hardware branch filtering, so privilege level
filtering is performed entirely in software. However, amd_brs_match_plm()
only validates the branch-to address against the requested privilege
levels. For branches from the kernel to user space, the branch-from
address is left unchecked and is leaked. Extend the software filter to
also validate the branch-from address, so that any branch record whose
branch-from address is in the kernel is dropped when
PERF_SAMPLE_BRANCH_USER is requested.15hCVE-2026-72078——
