Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ipv6: Fix potential uninit-value access in __ip6_make_skb()<br /> <br /> As it was done in commit fc1092f51567 ("ipv4: Fix uninit-value access in<br /> __ip_make_skb()") for IPv4, check FLOWI_FLAG_KNOWN_NH on fl6-&gt;flowi6_flags<br /> instead of testing HDRINCL on the socket to avoid a race condition which<br /> causes uninit-value access.
