Linux Kernel: AMD XDNA Accel Runtime Suspend Deadlock Fix
CVE-2026-43446 Published on May 8, 2026
accel/amdxdna: Fix runtime suspend deadlock when there is pending job
In the Linux kernel, the following vulnerability has been resolved:
accel/amdxdna: Fix runtime suspend deadlock when there is pending job
The runtime suspend callback drains the running job workqueue before
suspending the device. If a job is still executing and calls
pm_runtime_resume_and_get(), it can deadlock with the runtime suspend
path.
Fix this by moving pm_runtime_resume_and_get() from the job execution
routine to the job submission routine, ensuring the device is resumed
before the job is queued and avoiding the deadlock during runtime
suspend.
