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 kernel-rt-modules package and not the kernel-rt-modules 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.
