3.3 (Low) CVSS_V3 - CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N CVSS Calculator

Summary

[none]

Details

lxc-user-nic when asked to delete a network interface will 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. It may also be used to trigger side effects by causing a (read-only) open of special kernel files (ptmx, proc, sys). Affected releases are LXC: 2.0 versions above and including 2.0.9; 3.0 versions above and including 3.0.0, prior to 3.0.2.
