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. A use-after-free vulnerability was found in net/netfilter/nf_tables_api.c in the netfilter component in the Linux Kernel. This flaw can be exploited to achieve local privilege escalation. Adding and removing rules from chain bindings within the same transaction leads to a use-after-free issue.
