CVE-2017-14340 (GCVE-0-2017-14340)

Vulnerability from cvelistv5 – Published: 2017-09-15 11:00 – Updated: 2024-08-05 19:20

Summary

The XFS_IS_REALTIME_INODE macro in fs/xfs/xfs_linux.h in the Linux kernel before 4.13.2 does not verify that a filesystem has a realtime device, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) via vectors related to setting an RHINHERIT flag on a directory.
