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...

ROS-20261006-73-0071

The vulnerability of the ipv6srhrcv and seg6hmacvalidateskb functions in the Linux operating system is related to the use of pointers. Exploiting this vulnerability could allow an attacker to cause a service failure...

Linux kernel DoS

The vulnerability in the IPv6SRHRCV and SEG6HMACVALIDATESKB functions within the Linux kernel is related to dereferencing pointers. Exploitation of this vulnerability may allow an attacker to cause a denial of service...

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...
