CVE-2026-31454

Summary: CVE-2026-31454 affects the Linux kernel's XFS code. In xfs_inode_item_push() and xfs_qm_dquot_logitem_push(), the AIL lock is dropped to perform buffer IO, which can allow a log item to be freed during reclaim. A subsequent spin_lock() may dereference lip->li_ailp, causing a use-after...

CVE-2026-31455

CVE-2026-31455 pertains to the Linux kernel, specific to the XFS unmount path. During unmount, in xfs_unmount_flush_inodes(), the AIL is pushed while background reclaim and inodegc may still be running, which can lead to inodes being dirtied or re-queued into the AIL. The provided fix reorders th...

CVE-2026-31453

The CVE-2026-31453 issue affects the Linux kernel XFS path. The root cause is use-after-free-like behavior: after xfsaild_push_item() calls iop_push(), the log item could be freed if the AIL lock is dropped, allowing a freed log item to be dereferenced by tracepoints in the switch that follow. Th...
