Recommendation: Monitor — no exploitation signal at the moment.
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.
