--- Comment #2 from Christophe Leroy (christophe.leroy at c-s.fr) ---
Probably a bug in or around netlink_bind() in net/netlink/af_netlink.c
https://elixir.bootlin.com/linux/v5.6-rc1/source/net/netlink/af_netlink.c#L1017

Could you print the value of nlk->ngroups just before the loop which does the
test_bit() ? It shall be 32 or less.
