unconditionally open a user provided path. This code path may be used by
an unprivileged user to check for the existence of a path which they
wouldn’t otherwise be able to reach.

including special device files.
Workaround :

All LXC users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=app-emulation/lxc-2.1.1-r1'
