AI-suggested
A fix is available that replaces pm_runtime_get_sync() with pm_runtime_resume_and_get() in the rocket_job_run() function to properly handle error paths and release references. Users should apply the official kernel updates that include this fix for the affected Linux kernel versions.
Description
A vulnerability in the Linux kernel's accel/rocket component was fixed by correcting error path handling in the rocket_job_run() function. The issue involved reference leaks of dma_fence and runtime PM usage counters, and improper handling of fence states that could trigger warnings in the DRM scheduler. The fix replaced pm_runtime_get_sync() with pm_runtime_resume_and_get() to properly balance usage counters and release references on error.
