CVE-2024-27017

Local kernel compromise via PIPAPO dump race

Published May 1, 2024 · Updated Aug 5, 2026

Race condition in Linux kernel nftables PIPAPO sets allows local users to compromise the kernel through concurrent Netlink operations. The nft_pipapo_walk iterator selects a set view from a mutable generation mask, so a simultaneous transaction can switch the view and leave the dump walking stale data. Reaching the race requires Netlink control of a PIPAPO set and concurrent dump and update operations; successful exploitation can expose kernel data or redirect kernel control flow.
