High severity7.8NVD Advisory· Published Sep 27, 2023· Updated Jun 17, 2026

CVE-2023-5197

Description

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.
