Overview

CVE-2026-97601 is a known-severity vulnerability. It was published on September 25, 2026.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

ieee802154: 6lowpan: fix NULL dereference in lowpan_newlink

TUNSETLINK allows a TUN device to change its link-layer type to

ARPHRD_IEEE802154 without initializing ieee802154_ptr. lowpan_newlink()

checks only the device type before dereferencing the pointer, so an

RTM_NEWLINK request can trigger a NULL pointer dereference.

Reject devices without ieee802154_ptr along with devices of the wrong type.

How can CyberStrike help with CVE-2026-97601?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-97601 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
