In the Linux kernel, the following vulnerability has been resolved:
media: venus: hfi: add check to handle incorrect queue size
qsize represents size of shared queued between driver and video
firmware. Firmware can modify this value to an invalid large value. In
such situation, empty_space will be bigger than the space actually
available. Since new_wr_idx is not checked, so the following code will
result in an OOB write.
...
qsize = qhdr->q_size
if (wr_idx >= rd_idx)
empty_space = qsize - (wr_idx - rd_idx)
....
if (new_wr_idx < qsize) {
memcpy(wr_ptr, packet, dwords << 2) --> OOB write
Add check to ensure qsize is within the allocated size while
reading and writing packets into the queue.
