CVE-2026-43053

A flaw was found in the Linux kernel's XFS filesystem. During the inactivation of inodes with extended attributes, a specific timing window exists where a log shutdown can occur after some data blocks are invalidated but before the attribute map is fully truncated. This can lead to inconsistencie...
