Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: mm, slub: fixed a potential memory leak in kmemcacheopen. In the error path, the slub cache’s randomseq value might be leaked. This issue was addressed by using kmemcacherelease to release all relevant resources...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: mm/slub: Fixed the issue by returning errno if kmalloc fails. In createuniqueid, kmalloc, GFPKERNEL may fail due to out-of-memory conditions. If this happens, errno should be returned correctly instead of triggering a panic via...

RockyLinux 8 : kernel-rt (RLSA-2026:55765)

The remote RockyLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2026:55765 advisory. kernel: mm/slub: avoid accessing metadata when pointer is invalid in objecterr CVE-2025-39902 kernel: drm/amdkfd: Fix out-of-bounds write in...

kernel: mm/slub: avoid accessing metadata when pointer is invalid in object_err()

A flaw was found in the Linux kernel’s SLUB memory allocator mm/slub. The function objecterr — used for debugging object metadata freelist pointer, redzone, etc. — can access invalid pointers when reporting corruption, leading to a crash. In some cases, due to freelist corruption e.g., detected b...
