CVE-2019-15538

kernel: denial of service in in xfs_setattr_nonsize in fs/xfs/xfs_iops.c

Published Aug 25, 2019 CVSS 3.1 · 7.5 High EPSS 3.9% KEV · Not listed
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.
