CVE-2016-6197

Priority
Description
fs/overlayfs/dir.c in the OverlayFS filesystem implementation in the Linux
kernel before 4.6 does not properly verify the upper dentry before
proceeding with unlink and rename system-call processing, which allows
local users to cause a denial of service (system crash) via a rename system
call that specifies a self-hardlink.
Ubuntu-Description
It was discovered that the OverlayFS implementation in the Linux kernel did
not properly verify dentry state before proceeding with unlink and rename
operations. A local attacker could use this to cause a denial of service
(system crash).
