The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-013474 advisory.In the Linux kernel, the following vulnerability has been resolved:
netfilter: nft_set_pipapo: release elements in clone only from destroy path
Clone already always provides a current view of the lookup table, use it to destroy the set, otherwise it is possible to destroy elements twice.
This fix requires:

which came after:
