Vulnerability in Linux kernel (CVE-2026-93192)
Summary
Vulnerability in Linux kernel (CVE-2026-93192). Successful exploitation can lead to full system takeover.
Original description
The description as published by the source.
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.
