Public on 2023-09-27
Modified on 2024-01-12
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.
