CVE-2023-6817 (opens in a new tab)Amendment
The Rocky-Linux security team deemed this advisory irrelevant for Rocky-Linux:9.
NVD Description
Note: Versions mentioned in the description apply only to the upstream python3-perf-debuginfo package and not the python3-perf-debuginfo package as distributed by Rocky-Linux.
A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation.
The function nft_pipapo_walk did not skip inactive elements during set walk which could lead double deactivations of PIPAPO (Pile Packet Policies) elements, leading to use-after-free.
We recommend upgrading past commit 317eb9685095678f2c9f5a8189de698c5354316a.
