CVE-2019-15538

Priority
Description
An issue was discovered in xfs_setattr_nonsize in fs/xfs/xfs_iops.c in the
Linux kernel through 5.2.9. XFS partially wedges when a chgrp fails on
account of being out of disk quota. xfs_setattr_nonsize is failing to
unlock the ILOCK after the xfs_qm_vop_chown_reserve call fails. This is
primarily a local DoS attack vector, but it might result as well in remote
DoS if the XFS filesystem is exported for instance via NFS.
Ubuntu-Description
Benjamin Moody discovered that the XFS file system in the Linux kernel did
not properly handle an error condition when out of disk quota. A local
attacker could possibly use this to cause a denial of service.
