In the Linux kernel, the following vulnerability has been resolved:
ipv6: Fix potential uninit-value access in _ip6make_skb()
As it was done in commit fc1092f51567 ("ipv4: Fix uninit-value access in _ipmakeskb()") for IPv4, check FLOWIFLAGKNOWNNH on fl6->flowi6_flags instead of testing HDRINCL on the socket to avoid a race condition which causes uninit-value access.
