CVE-2026-93192 — drm/v3d: Clear queue->active_job when v3d_fence_create() fails

Affected: Linux

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

drm/v3d: Clear queue->active_job when v3d_fence_create() fails

The run_job() callbacks for BIN, RENDER, TFU and CSD assign the incoming job to queue->active_job before calling v3d_fence_create(). If v3d_fence_create() fails, the callback returns NULL without clearing active_job, leaving a dangling pointer.

Create a failure path in all run_job() callbacks that clears the active job before returning NULL. The BIN path takes queue->queue_lock around the clear as it races against v3d_overflow_mem_work(); RENDER, TFU and CSD paths have no concurrent reader, so the clear is lock-free.
