NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-zfcpdump-modules-core package and not the kernel-zfcpdump-modules-core package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

A use-after-free flaw was found in the Linux kernel's netfilter in the way a user triggers the nft_pipapo_remove function with the element, without a NFT_SET_EXT_KEY_END. This issue could allow a local user to crash the system or potentially escalate their privileges on the system.
