CVE-2026-63804

A flaw was found in the Linux kernel's GFS2 file system. This use-after-free vulnerability occurs when the gfs2qddealloc function attempts to access memory that has already been released during the unmounting process. This can lead to system instability or crashes, potentially resulting in a deni...
