CVE-2026-43101 (opens in a new tab)Amendment
The Red Hat security team deemed this advisory irrelevant for RHEL:10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream rv package and not the rv package as distributed by RHEL.
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.
