NVD Description

Note: Versions mentioned in the description apply only to the upstream linux-qemu-rc package and not the linux-qemu-rc package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

A use-after-free flaw was found in the netfilter subsystem of the Linux kernel. If the catchall element is garbage-collected when the pipapo set is removed, the element can be deactivated twice. This can cause a use-after-free issue on an NFT_CHAIN object or NFT_OBJECT object, allowing a local unprivileged user with CAP_NET_ADMIN capability to escalate their privileges on the system.
