Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: gfs2: The issue of “slab-use-after-free” was fixed in qdput. The commit a475c5dd16e5 states that “gfs2: The quota data objects were freed synchronously”. However, during system shutdown, quota data objects were actually freed...

CVE-2026-64418

A flaw was found in the Linux kernel's memory management mm shrinker subsystem. A race condition exists where the shrinkerinfo array can be prematurely freed while still accessible, leading to a use-after-free or double-free vulnerability. This memory corruption can be exploited by a local attack...
