CVE-2026-43446 Details
Description
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.
A deadlock vulnerability during runtime suspension has been identified in the Linux kernel's AMD XDNA acceleration component. This issue arises because the runtime suspend callback drains the job workqueue before suspending the device. If a job is still running and calls 'pm_runtime_resume_and_get()', it can create a deadlock with the suspend process. The vulnerability affects the Linux kernel stable tree.
Users can apply the patch available in the Linux kernel stable tree to address this vulnerability.
