Description
In the Linux kernel, the following vulnerability has been resolved: ipv6: ioam: fix potential NULL dereferences in __ioam6_fill_trace_data() We need to check __in6_dev_get() for possible NULL value, as suggested by Yiming Qian. Also add skb_dst_dev_rcu() instead of skb_dst_dev(), and two missing READ_ONCE(). Note that @dev can't be NULL.
