Published 2024-04-04

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: 212ed75dc5fb ("netfilter: nf_tables: integrate pipapo into commit protocol") which came after: 9827a0e6e23b ("netfilter: nft_set_pipapo: release elements in clone from abort path").
