CVE-2026-43158

CVE-2026-43158 is a Linux kernel XFS vulnerability where freemap adjustments in leaf blocks when adding xattrs can collide with the entries area, causing an assertion and potential filesystem shutdown (DoS). The root cause is incorrect freemap sizing/update logic in xfs_attr3_leaf_add_work, leadi...

CVE-2026-43153

CVE-2026-43153 affects the Linux kernel’s XFS attribute handling: the function xfs_attr_leaf_hasname has an problematic calling convention that can mishandle buffers. The fix is to open-code xfs_attr_leaf_hasname in callers so each caller of xfs_attr3_leaf_read manages buffer release. The issue i...
