# CVE-2026-80938

## Summary

- **CVE ID:** CVE-2026-80938
- **Severity:** UNKNOWN
- **CVSS Score:** 0
- **CWE:** N/A
- **Published:** Sep 11, 2026
- **Last Modified:** Sep 16, 2026

## Description

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

wifi: mt76: mt7615: avoid waiting for mac work under the mt76 mutex

mt7615_suspend() acquired the mt76 mutex and then called
cancel_delayed_work_sync() on mac_work.  mt7615_mac_work() acquires the
same mutex via mt7615_mutex_acquire() at the top of the worker, so if
mac_work is already running and blocked on the mutex, the suspend path
deadlocks waiting for the work it holds the mutex against.

Flush scan_work and mac_work before taking the mutex, matching the
suspend paths in mt7921 and mt7925.  scan_work only takes the mt76
spinlock, but moving it keeps the sequence consistent.  This also keeps
mac_work from running over an already suspended HIF, which the previous
split (async cancel under the lock, sync cancel after release) would
have allowed.
