Overview

CVE-2026-53317 is a medium-severity vulnerability. It was published on June 26, 2026 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

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

wifi: mt76: mt7921: Place upper limit on station AID

Any station configured with an AID over 20 causes a firmware crash.

This situation occurred in our testing using an AP interface on 7922

hardware, with a modified hostapd, sourced from Mediatek's OpenWRT

feeds.

In stock hostapd, station AIDs begin counting at 1, and this

configuration is prevented with an upper limit on associated stations.

However, the modified hostapd began allocation at 65, which caused the

firmware to crash. This fix does not allow these AIDs to work, but will

prevent the firmware crash.

This crash was only seen on IFTYPE_AP interfaces, and the fix does not

appear to have an effect on IFTYPE_STATION behavior.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.

How can CyberStrike help with CVE-2026-53317?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-53317 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.
