Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.17%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

In all android releases (Android for MSM, Firefox OS for MSM, QRD Android) from CAF using the linux kernel, Venus HW searches for start code when decoding input bit stream buffers. If start code is not found in entire buffer, there is over-fetch beyond allocation length. This leads to page fault.
