A flaw was found in the XFS file system in the Linux kernel. An acquired ILOCK was not freed/unlock when the call to xfs_qm_vop_chown_reserve fails and the lock is still held and can lead to denial to access for that device. This is primarily a local denial of service but could result in a remote denial of service if the XFS file system is exported as an NFS file system.
