Description Marian Rehak 2019-08-20 08:24:16 UTC

A flaw in the Linux kernels implementation of the ath6kl wireless network driver implementation could allow an attacker with physical access with custom USB hardware to plug in a rogue USB device that can possibly create a condition where the kernel will panic.

Red Hat does not include the code affected by this flaw in currently shipping releases.
