Technical description

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix array bounds error with may_goto may_goto uses an additional 8 bytes on the stack, which causes the interpreters[] array to go out of bounds when calculating index by stack_size. 1. If a BPF program is rewritten, re-evaluate the stack size. For non-JIT cases, reject loading directly. 2. For non-JIT cases, calculating interpreters[idx] may still cause out-of-bounds array access, and just warn about it. 3. For jit_requested cases, the execution of bpf_func also needs to be warned. So move the definition of function __bpf_prog_ret0_warn out of the macro definition CONFIG_BPF_JIT_ALWAYS_ON.

——0A maliciously crafted SVG file, when parsed through Autodesk 3ds Max, can force an Out-of-Bounds Read vulnerability. A malicious actor can leverage this vulnerability to cause a crash, read sensitive data, or execute arbitrary code in the context of the current process.8h CVE-2026-784756.1 MED

——0A flaw was found in the file-pix (ESM) plugin in GIMP. When processing a specially crafted PIX image file, the plugin allocates a Variable-Length Array (VLA) on the stack without proper bounds checking, causing an unbounded stack allocation followed by a 21-byte stack over-read. This can result in a denial of service due to stack exhaustion and a limited information disclosure of stack memory contents into an intermediate file.9h CVE-2026-781577.4 HIG

——4A vulnerability was detected in Open5GS 2.8.0. This affects the function pcrf_rx_aar_cb of the file src/pcrf/pcrf-rx-path.c of the component Rx AA-Request Handler. Performing a manipulation results in out-of-bounds read. It is possible to initiate the attack remotely. The patch is named c18dc6938bf63cc7374315d3dca303d92066e746. To fix this issue, it is recommended to deploy a patch.1d CVE-2026-780493.7 LOW

——10A vulnerability has been found in Systerel S2OPC up to 1.7.3. Impacted is the function SOPC_NodeMgtHelperInternal_AddVariableNodeAttributes of the file src/ClientServer/address_space/internal/sopc_node_mgt_helper_internal.c of the component AddNodes Service. The manipulation of the argument UserAccessLevel leads to out-of-bounds read. It is possible to initiate the attack remotely. A high degree of complexity is needed for the attack. The exploitability is considered difficult. The exploit has been disclosed to the public and may be used. The identifier of the patch is aafbd37d381b618312ebdf5ddf57027f62c14fdd. It is suggested to install a patch to address this issue.1d CVE-2026-772197.1 HIG

——1GNU Emacs before 31.0.91 contains an integer overflow in the PBM/PPM/PGM image loader that allows an attacker to leak heap memory contents by supplying a crafted image with large dimensions and an elevated max color index. The image loader multiplies image dimensions and channel count using signed integer arithmetic; for sufficiently large values, the result wraps to a negative number, bypassing the bounds check and causing the pixel reader to access heap memory past the end of the allocated buffer. The over-read contents are interpreted as pixel color values and rendered on screen.4d CVE-2026-772376.5 MED

——1Missing queue-set type validation in xQueueAddToSet() in the FreeRTOS-Kernel before 11.3.1 might allow an unprivileged task on MPU-enabled ports with configUSE_QUEUE_SETS=1 to read privileged kernel memory. To remediate this issue, users should upgrade to version 11.3.1 or later.6h
