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.
AnalysisAI
Deadlock in the Linux kernel's AMD XDna accelerator driver (accel/amdxdna) causes a local denial-of-service by hanging the runtime power management subsystem. An authenticated local user who triggers job execution on the AMD XDna accelerator while the system simultaneously attempts a runtime suspend can lock the kernel indefinitely. …
