CVE-2023-5197

A use-after-free vulnerability was found in net/netfilter/nf_tables_api.c in the netfilter component in the Linux Kernel. This flaw can be exploited to achieve local privilege escalation. Adding and removing rules from chain bindings within the same transaction leads to a use-after-free issue.

Mitigation

Mitigation for this issue is to skip loading the affected module "netfilter" onto the system until we have a fix available. This can be done by a blacklist mechanism and will ensure the driver is not loaded at the boot time.

How do I blacklist a kernel module to prevent it from loading automatically?
