Vulnerability details
The vulnerability allows a local user to compromise system confidentiality, integrity, and availability.
The vulnerability exists due to failure to clear a dangling active-job pointer in the Linux kernel V3D driver's BIN, RENDER, TFU, and CSD job execution callbacks when v3d_fence_create() fails during job execution. A local user can exploit the stale queue->active_job reference to compromise system confidentiality, integrity, and availability.
The BIN queue's active-job reference can also be accessed concurrently by v3d_overflow_mem_work().
Affected software
