Descripción técnica

In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: Correct tid cleanup when tid setup fails Currently, if any error occurs during ath12k_dp_rx_peer_tid_setup(), the tid value is already incremented, even though the corresponding TID is not actually allocated. Proceed to ath12k_dp_rx_peer_tid_delete() starting from unallocated tid, which might leads to freeing unallocated TID and cause potential crash or out-of-bounds access. Hence, fix by correctly decrementing tid before cleanup to match only the successfully allocated TIDs. Also, remove tid-- from failure case of ath12k_dp_rx_peer_frag_setup(), as decrementing the tid before cleanup in loop will take care of this. Compile tested only.

——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.11h CVE-2026-781577.4 ALT

——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 BAJ

——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 ALT

——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
