kernel: xfs: fix freemap adjustments when adding xattrs to leaf blocks

A flaw was found in the Linux kernel's XFS filesystem. When adding extended attributes xattrs, which are metadata associated with files, to leaf blocks, incorrect adjustments to the freemap can occur. This inconsistency allows the entries array and free space to overlap, leading to an assertion...

CVE-2026-45858

A flaw was found in the Linux kernel's ext4 filesystem. This vulnerability occurs during the splitting of unwritten data blocks, where a portion of the data may be incorrectly marked as written while still containing stale, uninitialized information. A local attacker could potentially exploit thi...
