A flaw was found in the Linux kernel’s TUN/TAP functionality. This issue could allow a local user to bypass network filters and get unauthorized access to some resources.
To mitigate this issue, prevent modules tap and tun from being loaded. Please see <https://access.redhat.com/solutions/41278> for how to blacklist a kernel module to prevent it from loading automatically.
