CVSS 2.0
6.9
MediumMetricsAV:L/AC:M/Au:N/C:C/I:C/A:C
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 4.2.4
Description
The issue allows local users to bypass an intended container protection mechanism by renaming a directory, related to a "double-chroot attack." This occurs because the prepend path function in fs/dcache.c does not properly handle rename actions inside a bind mount.
Recommendations
For Linux kernel versions prior to 4.2.4, update to version 4.2.4 or later to resolve the issue. As a temporary workaround, consider restricting access to the rename functionality inside bind mounts to minimize the risk of exploitation.
