CVE-2026-98444 xfs: drop dquot flush lock when we can't find a buffer to flush

In the Linux kernel, the following vulnerability has been resolved: xfs: drop dquot flush lock when we can't find a buffer to flush LOLLM noticed that xfsqmflushone fails to drop the dquot flush lock if it can't grab the buffer associated with the dquot. Since there's no buffer, nobody else is...

CVE-2026-98444

The Linux kernel contains a vulnerability in the xfs filesystem where the xfs_qm_flush_one function fails to release the dquot flush lock (dqflock) when it is unable to acquire the associated buffer. Because the lock remains held when no buffer exists for other processes to release it, the system...

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...
