CVE-2026-23442

Description

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.
