The commit 3c52c6bb831f (tcp/udp: Fix memory leak in ipv6_renew_options()) fixes a memory leak reported by syzbot. This seems to be a good candidate for the stable trees. This patch didn't apply cleanly in 5.15 kernel, since release_sock() calls are changed to sockopt_release_sock() in the latest kernel versions.
