kernel: ipv6: add NULL checks for idev in SRv6 paths

A flaw was found in the Linux kernel. Missing null pointer checks in the IPv6 Segment Routing SRv6 implementation, specifically within the seg6hmacvalidateskb and ipv6srhrcv functions, can occur when an IPv6 device lacks proper configuration. This oversight may allow an attacker to trigger a null...

CVE-2026-23442: NULL Pointer Dereference

In the Linux kernel, the following vulnerability has been resolved: ipv6: add NULL checks for idev in SRv6 paths in6devget can return NULL when the device has no IPv6 configuration e.g. MTU IPV6MINMTU or after NETDEVUNREGISTER. Add NULL checks for idev returned by in6devget in both...
