CVE-2023-5197: Use-after-free in Linux kernel's netfilter: nf_tables component

First published: Tue Sep 26 2023(Updated: )

A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. Addition and removal of rules from chain bindings within the same transaction causes leads to use-after-free. We recommend upgrading past commit f15f29fd4779be8a418b66e9d52979bb6d6c2325.
