Vulnerability from github – Published: 2026-03-25 12:30 – Updated: 2026-05-29 15:30

Details

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

accel/amdxdna: Fix dead lock for suspend and resume

When an application issues a query IOCTL while auto suspend is running, a deadlock can occur. The query path holds dev_lock and then calls pm_runtime_resume_and_get(), which waits for the ongoing suspend to complete. Meanwhile, the suspend callback attempts to acquire dev_lock and blocks, resulting in a deadlock.

Fix this by releasing dev_lock before calling pm_runtime_resume_and_get() and reacquiring it after the call completes. Also acquire dev_lock in the resume callback to keep the locking consistent.

Severity

5.5 (Medium)
