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.
