On some hardware revisions where VP9 decoding is hardware-accelerated, the frame size is not programmed correctly into the decoder hardware which can lead to an invalid memory access by the decoder.
The product performs pointer arithmetic on a valid pointer, but it uses an offset that can point outside of the intended range of valid memory locations for the resulting pointer.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
