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

accel/rocket: Fix error path handling in rocket_job_run()

In rocket_job_run(), after taking an extra fence reference for
job->done_fence via dma_fence_get(), the error paths have three bugs:

- The dma_fence reference held by job->done_fence is never released,
causing a reference leak.
- pm_runtime_get_sync() increments the usage counter even on failure,
but the error path does not decrement it, leaking the runtime PM
reference and preventing the NPU from suspending.
- A valid but unsignaled fence is returned to the DRM scheduler,
which triggers WARN("Fence ... released with pending signals!")
when the scheduler drops its reference.

Fix by replacing pm_runtime_get_sync() with pm_runtime_resume_and_get()
which auto-balances the usage counter on failure, releasing both fence
references on error, and returning ERR_PTR(ret) instead of the
unsignaled fence.
