Description

It was found that stacking a file system over procfs in the Linux kernel could lead to a kernel stack overflow due to deep nesting, as demonstrated by mounting ecryptfs over procfs and creating a recursion by mapping /proc/environ. An unprivileged, local user could potentially use this flaw to escalate their privileges on the system.

Statement

This issue affects the Linux kernels as shipped with Red Hat Enterprise Linux 5 and 6 and may addressed in a future update.
