CVE-2023-4015 – Use-after-free in Linux kernel's netfilter: nf_tables component
https://notcve.org/view.php?id=CVE-2023-4015
30 Aug 2023 — 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.
