This issue:
https://github.com/torvalds/linux/commit/b29c457a6511435960115c0f548c4360d5f4801d
[Impact]
Data corruption and/or leak.
[Fix]
Zero out entire data structure beforehand

Boot-test only so far.
[Regression Potential]
Possible effect on iptables/nftables. Though considered minimal risk as the
patch has only a very localized effect and is accepted upstream in v5.12
