Denial of Service Vulnerability in OverlayFS on Linux Kernel by Linux
CVE-2016-6197
5.5MEDIUM
Summary
The vulnerability in the OverlayFS filesystem implementation allows local users to exploit insufficient verification of the upper dentry. This oversight during unlink and rename system-call processing can lead to a denial of service, causing the system to crash when a self-hardlink is created using a rename system call. Affected systems may experience significant disruption, and users should consider upgrading to later versions to mitigate this issue.
