In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
drm\/v3d: Clear queue->active_job when v3d_fence_create() fails<\/p>\n
The run_job() callbacks for BIN, RENDER, TFU and CSD assign the incoming
\njob to queue->active_job before calling v3d_fence_create(). If
\nv3d_fence_create() fails, the callback returns NULL without clearing
\nactive_job, leaving a dangling pointer.<\/p>\n
Create a failure path in all run_job() callbacks that clears the active
\njob before returning NULL. The BIN path takes queue->queue_lock around the
\nclear as it races against v3d_overflow_mem_work(); RENDER, TFU and CSD
\npaths have no concurrent reader, so the clear is lock-free.<\/p>\n","protected":false},"excerpt":{"rendered":"
