Published Jun 24, 2026CWE-667EPSS 0.13%

Overview

CVE-2026-53101 is a medium-severity vulnerability. It was published on June 24, 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: fix potential deadlock in mt7921_roc_abort_sync

roc_abort_sync() can deadlock with roc_work(). roc_work() holds

dev->mt76.mutex, while cancel_work_sync() waits for roc_work()

to finish. If the caller already owns the same mutex, both

sides block and no progress is possible.

This deadlock can occur during station removal when

mt76_sta_state() -> mt76_sta_remove() -> mt7921_mac_sta_remove() ->

mt7921_roc_abort_sync() invokes cancel_work_sync() while

roc_work() is still running and holding dev->mt76.mutex.

This avoids the mutex deadlock and preserves exactly-once

work ownership.

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-2026-53101?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-53101 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.
