Description
CVE-2024-27017 is a high-severity vulnerability in the Linux kernel's netfilter nft_set_pipapo component. It involves an issue where the generation mask can be updated during a netlink dump, causing the pipapo set backend walk iterator to incorrectly infer the data structure view. This flaw has been resolved by adding notation to specify user intent for reading or updating the set. Multiple Ubuntu kernel versions are affected, and patches have been released to address the issue.
