Overview
CVE-2026-90370 is a known-severity vulnerability. It was published on September 17, 2026.
Technical description
In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7996: bound TLV walk in mt7996_mcu_get_chip_config
The response TLV loop advanced by tlv->len without a minimum, so a
theoretical firmware response containing a zero-length TLV could spin
forever, hanging the CPU during device probe.
The u32 payload was also read without bounds checking.
Reject a short fixed field, stop on a TLV whose length underruns the
header or overruns the skb.

How can CyberStrike help with CVE-2026-90370?
CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-90370 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.
