In the Linux kernel, the following vulnerability has been resolved:
ipv6: add NULL checks for idev in SRv6 paths
in6 dev get() can return NULL when the device has no IPv6 configuration
(e.g. MTU < IPV6 MIN MTU or after NETDEV UNREGISTER).
Add NULL checks for idev returned by in6 dev get() in both
seg6 hmac validate skb() and ipv6 srh rcv() to prevent potential NULL
pointer dereferences.
