JSON

A memory corruption flaw was found in the Linux kernel’s Netfilter subsystem in the way a local user uses the libnetfilter_queue when analyzing a corrupted network packet. This flaw allows a local user to crash the system or a remote user to crash the system when the libnetfilter_queue is used by a local user.

Mitigation

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