A NULL pointer dereference flaw was found in the way the Line 6 POD USB driver in the Linux kernel handled disconnection. This flaw allows an attacker with physical access to the system to crash the system.

Mitigation

To mitigate this issue, prevent module snd-usb-line6 from being loaded. Please see <https://access.redhat.com/solutions/41278&gt; for how to blacklist a kernel module to prevent it from loading automatically.
