A flaw was found in the way the mwifiex PCIE driver in the Linux kernel handled resource cleanup on a DMA mapping error. This flaw allows an attacker able to trigger the DMA mapping error to crash the system.
In order to mitigate this issue it is possible to prevent the affected code from being loaded by blacklisting the kernel module mwifiex_pcie. For instructions relating to how to blacklist a kernel module refer to: <https://access.redhat.com/solutions/41278> .
