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.
