CVE-2026-53343

The CVE-2026-53343 entry documents a Linux kernel ARM vulnerability patch: in configurations with KASAN_VMALLOC and VMAP_STACK, a dummy read from the KASAN VMAP shadow in __switch_to() used an unaligned word load (ldr) which can fault on ARMv5 and crash ARM926/VersatilePB; the fix switches to a b...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Use kvfree instead of kfree in amdgpugmcgetnpsmemranges. The amdgpudiscoverygetnpsinfo function internally allocates memory for ranges using kvcalloc, which may use vmalloc for large allocations. Using kfree to releas...

CVE-2026-46281

A flaw was found in the Linux kernel. When shrinking a vmalloc allocation using the vreallocnodealign function, if the requested new size is smaller than the old size, an out-of-bounds write can occur. This memory corruption vulnerability could allow a local attacker to cause a denial of service ...

CVE-2026-46281

CVE-2026-46281 affects the Linux kernel vmalloc path used by vrealloc when a new allocation is forced (wrong NUMA node or alignment). The code copies old_size bytes into a newly allocated buffer of size bytes during a shrink request, which can cause an out-of-bounds write. The fix bounds the copy...
