SUSE CVE-2026-43158

In the Linux kernel, the following vulnerability has been resolved: xfs: fix freemap adjustments when adding xattrs to leaf blocks xfs/592 and xfs/794 both trip this assertion in the leaf block freemap adjustment code after 20 minutes of running on my test VMs: ASSERTichdr-firstused = ichdr-count...

CVE-2026-43158

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-2026-43153

A flaw was found in the Linux kernel's XFS filesystem. The xfsattrleafhasname function has a problematic calling convention that can lead to incorrect buffer handling. This issue can result in the use of already released memory buffers, potentially causing memory corruption or system instability....

CVE-2026-43187

Summary: CVE-2026-43187 affects the Linux kernel XFS freemap handling in xattr leaf entries. The root cause is a bug in the freemap update logic in _leaf_add that can leave behind zero‑length freemap entries with a nonzero base, and later entries could be updated incorrectly so freemap entries ov...
