CVE-2019-15538

Public on 2019-08-25
Modified on 2019-09-18
Description

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.
