CVE-2026-52922

A flaw was found in the Linux kernel's batman-adv Better Approach To Mobile Ad-hoc Networking module. This vulnerability occurs because the batadvdatforwarddata function fails to validate the success of a memory allocation operation. An attacker could exploit this by triggering a scenario where t...

Astra Linux – Vulnerability in imagemagick

ImageMagick is free and open-source software used for editing and manipulating digital images. Before versions 7.1.2-16 and 6.9.13-41, there was a vulnerability where a memory allocation failure in the sixel encoder could lead to writing beyond the end of a buffer on the stack. This vulnerability...

In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: ipc4-topology: Corrected the allocation size for bytes controls. The size of the data behind scontrol-ipccontroldata for bytes controls is as follows: 1 sizeofstruct sofipc4controldata + // kernel-only struct 2...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: block: fixed a memory leak in blkdevissuezeropages. The check for the fatal signal was moved before the bioalloc function, to prevent a memory leak when BLKDEVZEROKILLABLE is set and a fatal signal is pending. Previously, the bio...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: gfs2: Prevent recursive memory reclamation The new inode function returns a new inode with inode-imapping-gfpmask set to GFPHIGHUSERMOVABLE. This value includes the GFPFS flag, allowing allocations in that address space to...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: drm/xe: Set numsyncs to a limit to prevent excessively large allocations. The exec and vmbind ioctls allow userspace to specify an arbitrary value for numsyncs. Without bounds checking, a very large value of numsyncs can result i...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: drm/buddy: This issue was addressed by validating the rounded allocation size before proceeding with the allocation process. When the DRMBUDDYCONTIGUOUSALLOCATION flag is set, the requested allocation size is rounded up to the ne...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: Media: Verisilicon: AV1 – Fix for the tile info buffer size. Each tile consists of: rowsb, colsb, startpos, and endpos 4 bytes each. Therefore, the total memory required is AV1MAXTILES 16 bytes. Use the correct define to allocate...

In the Linux kernel, the following vulnerabilities have been resolved: mm/pagealloc: The migrate type of all pageblocks during coalescence has been changed. When a page is freed, it coalesces with a buddy page into a higher-order page whenever possible. When the migrate type of the buddy page...

Astra Linux – Vulnerability in imagemagick

ImageMagick is free and open-source software used for editing and manipulating digital images. Before versions 7.1.2-15 and 6.9.13-40, a specially crafted SVG file containing a malicious element would cause ImageMagick to attempt to allocate approximately 674 GB of memory, resulting in a...

Astra Linux – Vulnerability in Qemu

A flaw was discovered in the virtio-crypto device of QEMU. A malicious guest operating system can exploit a missing length limit in the AKCIPHER path, resulting in uncontrolled memory allocation. This can lead to a denial of service attack on the host system, causing the QEMU process to terminate...

CVE-2026-11586
