CVE-2026-98443

A flaw in the Linux kernel's XFS file system regarding cursor and pointer handling during the recovery of iunlink buckets allows for a use-after-free (UAF) condition. Specifically, in xlog_recover_iunlink_bucket, failing to null out prev_ip after release can lead to UAF if an inodegc flush call f...
