A NULL pointer dereference flaw was found in the Linux kernel’s netfilter subsystem. The issue could occur due to an error in nf_tables_updtable while freeing a transaction object not placed on the list head. This flaw allows a local, unprivileged user to crash the system, resulting in a denial of service.
This flaw can be mitigated by preventing the affected netfilter kernel module from being loaded. For instructions on how to blacklist a kernel module, please see <https://access.redhat.com/solutions/41278>.
