Vulnerability from github – Published: 2023-09-27 15:30 – Updated: 2025-02-13 18:31

Details

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.

Severity

7.8 (High)
