| Doc Text: |
A use-after-free flaw was found in the Linux kernel's netfilter: nf_tables component, which can be exploited to achieve local privilege escalation. When nf_tables_delrule() is flushing table rules, it is not checked whether the chain is bound, and the chain's owner rule can release the objects in certain circumstances.
