JSON

A buffer overflow flaw was found in the Linux kernel Broadcom Full MAC Wi-Fi driver. This issue occurs when a user connects to a malicious USB device. This can allow a local user to crash the system or escalate their privileges.

Mitigation

To mitigate this issue, prevent the brcmfmac module from being loaded. See <https://access.redhat.com/solutions/41278> for how to blacklist a kernel module to prevent it from loading automatically.
