## Description

The scm\_check\_creds function in net/core/scm.c in the Linux kernel before
3.8.6 does not properly enforce capability requirements for controlling the
PID value associated with a UNIX domain socket, which allows local users to
bypass intended access restrictions by leveraging the time interval during
which a user namespace has been created but a PID namespace has not been
created.
