——2OW2 ASM 5.0 before 9.11 contains an excessive memory allocation vulnerability in ClassReader.readBootstrapMethodsAttribute() that sizes an int array from num_bootstrap_methods without validating attribute_length. Attackers can supply a crafted class file of about 100 bytes that forces roughly 2 GB allocation, causing an OutOfMemoryError that crashes the JVM or consuming thread.7dCVE-2026-1073816.5 MED34.9%
——10svg-sanitizer is a PHP SVG/XML sanitizer. Prior to 1.0.0, Resolver::processReferences() in src/ElementReference/Resolver.php builds the SVG <use> reference graph with a case-sensitive href attribute predicate before cleanHrefAttributes() normalizes mixed-case names. An attacker can provide xlink:HrEf on nested <use> elements so the graph omits those references, after which the sanitizer converts the attribute to canonical xlink:href and returns the live nesting structure without applying the useNestingLimit protection. A consuming application that renders the sanitized SVG can therefore be exposed to the resource exhaustion that control is designed to prevent. This issue is fixed in version 1.0.0.4dCVE-2026-1049397.5 HIG28.2%
——8Description
NGINX Ingress Controller has a vulnerability when implementing an externalAuth policy for ingress. NGINX Ingress Controller may mishandle the HTTP response from an OAuth IdP and allow an attacker to acquire unauthenticated access to protected paths before the proper external authentication can happen.
Impact
This vulnerability may allow remote attackers
unauthenticated
access to protected
paths. There is no control plane exposure; this is a data plane issue only.
Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.6dCVE-2026-101895—52.9%
——16Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to 20.3.31, 21.2.23, and 22.1.6, the @angular/platform-server DOM emulation parser can enter an infinite synchronous loop when Angular server-side rendering processes attacker-controlled HTML containing an incomplete DOCTYPE that ends with whitespace at end of input. In Domino lib/HTMLParser.js, after_doctype_name_state emits doctype and EOF tokens without advancing nextchar or leaving the fixed-lookahead state, so the scanner repeatedly handles the same EOF marker. A remote unauthenticated attacker can use this condition through server-side HTML parsing paths such as innerHTML binding to consume a Node.js SSR worker at full CPU, starve the event loop, and stop concurrent and subsequent requests. This issue is fixed in versions 20.3.31, 21.2.23, and 22.1.6.5dCVE-2026-1010255.3 MED23.1%
——7Description
NGINX JavaScript (njs) has a vulnerability where the built-in njs engine leaks a libxml2 parser context when xml.parse() fails. The failure path did not register cleanup and the context was not released for the lifetime of the process. An unauthenticated attacker may send requests with malformed XML and can cause unbounded memory growth in long-lived NGINX worker processes.
Impact
This vulnerability may allow remote attackers to send requests that trigger repeated parsing of malformed XML and may lead to NGINX worker termination or denial of service. There is no control plane exposure; this is a data plane issue only.
Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.6dCVE-2026-1010196.5 MED9.2%
——3Description
NGINX JavaScript (njs) has a vulnerability where the njs XML module exposes entity-backed XML attributes inconsistently with libxml2 canonicalization. In both the built-in njs and QuickJS backends during the canonicalization process, the $attr$Name getter may return undefined for an explicitly present attribute containing an internal entity reference. The $attrs getter may return a value derived only from the first attribute child. This may allow an unauthenticated attacker that invests significant effort in obtaining a genuinely signed document to skip validation while signature verification succeeds. An nginx-saml deployment is a confirmed affected consumer when run with the built-in njs backend.
Impact
In affected signed-XML consumers, an unauthenticated attacker can cause security-relevant attributes to appear absent or truncated while signature verification succeeds. In nginx-saml, this can bypass expiry, Destination, and request-correlation checks, enabling replay or acceptance of a response outside its intended context. It does not permit signature or identity forgery, or a direct availability impact. There is no control plane exposure; this is a data plane issue only.
Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.6dCVE-2025-714337.5 HIG46.3%
——14Kaneo before 2.1.6 contains a missing authorization vulnerability that allows authenticated users to access other workspaces by supplying project, task, label or workspace identifiers to API routes lacking membership checks. Attackers who obtain identifiers, for example from shared project links, can read projects and tasks, modify or delete tasks, labels and comments, and search workspace contents.5dCVE-2024-583923.3 LOW5.7%
——2PhysicsFS through 3.2.0 contains an out-of-bounds read vulnerability in __PHYSFS_utf8codepoint() that allows attackers to read past name buffers via an off-by-one cursor advance on six-octet UTF-8 sequences. Attackers can supply a crafted archive with entry names ending in six-octet sequences, causing PHYSFS_utf8stricmp() and hashing to over-read and crash the application.2dCVE-2020-372829.8 CRI87.3%
——26office-converter through 1.0.2 contains an OS command injection vulnerability that allows attackers to execute commands by supplying a crafted fileName to generatePdf() or generateHtml(). Attackers can embed $(...), backticks, or a closing quote with shell metacharacters in the file name, which is concatenated into an unoconv command run via child_process.exec(), executing commands with Node.js process privileges.5dCVE-2020-372818.1 HIG58.5%
——18Gravitee API Management through 4.12.22 contains an authentication bypass vulnerability that allows unauthenticated remote attackers to impersonate any user by forging JWTs signed with the shipped default jwt.secret. Attackers knowing an existing user ID can sign an HS256 token with that subject and present it as a bearer token to the Management API, impersonating administrators to gain full platform control.7dCVE-2017-202867.8 HIG9.5%
——3DevIL through 1.8.0 contains a heap-based buffer overflow in iGetPalette() in il_gif.cpp that allows attackers to write beyond a 768-byte palette buffer when loading GIF images. Attackers can supply a crafted two-frame GIF whose second frame uses disposal method 1 with a local colour table, writing up to 384 controlled bytes past the heap allocation and possibly executing code.5dCVE-2016-200995.5 MED13.8%
——4L-SMASH through 2.14.5 contains an infinite loop vulnerability in vc1_importer_probe() in importer/vc1_imp.c that allows attackers to hang applications via crafted input files. Attackers can supply a file consisting only of zero bytes, which lsmash_read_file() probes automatically, causing indefinite CPU consumption and denial of service.5dCVE-2026-98431—9.0%
——3In the Linux kernel, the following vulnerability has been resolved:
RDMA/uverbs: Fix mmap_lock/disassociation_lock circular dependency
Commit 51976c6cd786 ("RDMA/core: Provide rdma_user_mmap_disassociate()
to disassociate mmap pages") introduced disassociation_lock to protect
new mmap registrations against uverbs_user_mmap_disassociate(), but
created an ABBA deadlock:
Thread A (mmap / fork):
mmap_lock -> disassociation_lock
Thread B (disassociate):
disassociation_lock -> mmap_lock
Fix by removing disassociation_lock entirely and using the pre-existing
hw_destroy_rwsem instead. hw_destroy_rwsem already provides the same
protection: rdma_umap_open() and ib_uverbs_mmap() both use
down_read_trylock() before registering a new VMA, so holding hw_destroy_rwsem
in uverbs_user_mmap_disassociate() is sufficient to block new registrations.
trylock is used in both mmap paths (not blocking down_read) because
mmap_lock is already held on entry, and uverbs_user_mmap_disassociate()
acquires mmap_lock internally — a blocking read would recreate the same
deadlock.
The only caller that was not taking hw_destroy_rwsem for write was
rdma_user_mmap_disassociate(). Fix it to take the rwsem per-ufile while
iterating under lists_mutex. This is safe because ib_uverbs_close()
releases hw_destroy_rwsem entirely before acquiring lists_mutex, so the
two locks are never held simultaneously.

——3In the Linux kernel, the following vulnerability has been resolved:
RDMA/efa: Keep admin queues alive while IRQ is registered
The management IRQ handler accesses both the admin completion queue and the
async event queue. The driver registered the IRQ before constructing these
queues and destroyed them before freeing the IRQ, so the handler's lifetime
was not contained by the resources it accesses.
Initialize the queues with interrupts masked, request the IRQ, and then
switch to interrupt mode. On removal, reset the device and free the IRQ
before destroying the queues. Also reset the device before destroying the
queues if IRQ registration fails, because the device already has their DMA
addresses.3dCVE-2026-98429—11.2%
——3In the Linux kernel, the following vulnerability has been resolved:
RDMA/efa: Keep EQ resources alive while IRQ is registered
The completion IRQ handler accesses the EQ state and DMA buffer. Its IRQ was
registered before that state was initialized, while teardown released the
buffer before free_irq() synchronized the handler.
Initialize the EQ without arming it, register the IRQ, and then arm it.
Reverse the resource order during teardown by freeing the IRQ before
destroying the EQ.3dCVE-2026-98428—11.2%
——3In the Linux kernel, the following vulnerability has been resolved:
ALSA: usb: 6fire: Avoid embedded URBs
The USB 6fire driver uses URBs embedded in different structs for PCM,
MIDI and communication, and this is basically a buggy implementation
nowadays; since a URB is managed with a refcount, this may lead to a
UAF when the URB is released asynchronously.
For addressing the problem, this patch converts those embedded URBs to
ones that are properly allocated via usb_alloc_urb(). The
pcm_urb.packets[] is gone, as it's allocated by usb_alloc_urb(), hence
it's found in urb.iso_frame_desc[] instead.
The conversions are rather straightforward; each embedded struct urb
is changed to a pointer, and its callers are updated accordingly.
The resource for those structs are released in the common destructor
functions (usb6fire_comm_free(), etc), which are called at both the
init error path and the disconnect.
No functional changes, only compile-tested.3dCVE-2026-98427—9.0%
——3In the Linux kernel, the following vulnerability has been resolved:
net/sched: codel: bound the dropping loop per dequeue call
The CoDel control law schedules the next drop one interval/sqrt(count)
after the previous drop, using the configured interval
(codel_params.interval). For very small intervals the scheduled step
rounds down to zero, so the dropping loop in codel_dequeue() never
advances and drains the entire backlog under the qdisc lock in one
call - an unprivileged user can trigger a soft lockup this way.
Fix in the shared codel code used by both codel and fq_codel:
1. Make the control-law step at least 1 tick so the dropping loop
always moves forward.
2. Cap the dropping loop at CODEL_MAX_DROPS_PER_DEQUEUE (256) drops
per codel_dequeue() call, resyncing drop_next to now when the cap
is hit: the catch-up owed to the loop grows with the idle gap and
the backlog, which no interval threshold can bound. This is a
deliberate behaviour change after long idle gaps.
The cap applies to fq_codel (4b549a2ef4be) and the mac80211 TXQ path
(fixed interval, cap only).
The target sojourn delay (codel_params.target) is not validated: it
does not feed the control law, so a sub-tick value is aggressive
rather than deadlock-prone.
Conditions to recreate the bug:
- tc qdisc add dev lo root handle 1: tbf rate 1kbit burst 2kb limit 1000000
- tc qdisc add dev lo parent 1:1 handle 10: codel interval 2us target 1ms noecn limit 1000000 (same for fq_codel)
- unpatched kernel: tc accepts it; a UDP flood under the 1kbit tbf
soft-lockups (watchdog: BUG: soft lockup) while one
codel_dequeue() call drops the backlog under the qdisc lock
- patched kernel: same setup, at most 256 drops per dequeue call,
no soft lockup
Testing: claim reproducer and interval 2us/3us variants run clean;
tdc qdisc category passes (see the selftests patch).3dCVE-2026-98426—11.8%
——4In the Linux kernel, the following vulnerability has been resolved:
wifi: mwifiex: fix IRQ leak using wrong index in MSI-X error path
mwifiex_pcie_request_irq() registers each MSI-X vector with a per-index
dev_id (&card->msix_ctx[i]). On a request_irq() failure the cleanup loop
"for (j = 0; j < i; j++)" frees msix_entries[j].vector but passes the
failed index's &card->msix_ctx[i] as the dev_id. free_irq() matches on
(irq, dev_id), so it fails to find the action registered with
&card->msix_ctx[j]: the already-requested IRQ j is not freed (leaked) and
free_irq() warns about freeing a non-existent IRQ. Use &card->msix_ctx[j].3dCVE-2026-98425—10.5%
——3In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: don't warn when an IBSS has no channel to scan
ieee80211_request_ibss_scan() warns when regulatory leaves no
allowed channel, but that can happen as the regdomain can change
while IBSS is operating, and it can continue to operate briefly
during the 60s grace period until it's shut down.
Just remove the warning in this case.3dCVE-2026-98424—10.2%
——3In the Linux kernel, the following vulnerability has been resolved:
wifi: cfg80211: undo netns switch if renaming the wiphy fails
Once all the interfaces have been moved, cfg80211_switch_netns()
moves the wiphy itself by setting its network namespace and then
renaming it, which makes sysfs move it. The rename can fail (but
only on allocation failures), leaving things mixed up and hitting
the warning there.
Ignoring it isn't great, undo the move and let the change fail
in this case. If undo fails then WARN, then things would again
be stuck in two different network namespaces.3dCVE-2026-98423—11.2%
——3In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211_hwsim: don't hand frames to mac80211 while stopping
The code checks ->started for frames coming from wmediumd, but the
radio can be stopped after the check and before frame delivery,
causing mac80211 to hit the WARN_ON(!local->started).
Expand the mutex for this case and synchronise against it when the
radio is stopped to avoid being able to hit the warning with hwsim.
Drop the error print that would've complicated the error path, it
only triggers for allocation failures (already noisy) and malformed
frames anyway.3dCVE-2026-98422—11.8%
——4In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: reset the AP_VLAN tailroom counter on ifdown
On ifup, AP_VLAN interfaces get crypto_tx_tailroom_needed_cnt from
the AP interface, but it's never decremented again unless the AP is
also brought down. Thus, bringing the same AP_VLAN up again will
increment the counter again and eventually hit the sanity check:
WARN_ON_ONCE(sdata->crypto_tx_tailroom_needed_cnt !=
master->crypto_tx_tailroom_needed_cnt);
Reset it on ifdown to avoid that.3d
