A use-after-free vulnerability in the Linux kernel’s netfilter: nf_tables
component can be exploited to achieve local privilege escalation. On an
error when building a nftables rule, deactivating immediate expressions in
nft_immediate_deactivate() can lead unbinding the chain and objects be
deactivated but later used. We recommend upgrading past commit
0a771f7b266b02d262900c75f1e175c7fe76fec2.

Notes

Author Note
Priority reason: By using unprivileged user namespaces, this can be exploited to achieve local privilege escalation.
