CVE-2026-98444

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 xfs qm flush one 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 going to drop the dqflock, so we need to do it ourselves.
