- Summary
- xfs: scrub: unlock dquot before early return in quota scrub
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
xfs: scrub: unlock dquot before early return in quota scrub
xchkquotaitem can return early after calling xchkfblockprocesserror. When that helper returns false, the function returned immediately without dropping dq->qqlock, which can leave the dquot lock held and risk lock leaks or deadlocks in later quota operations.
Fix this by unlocking dq->q_qlock before the early return.
