In Android before 2018-04-05 or earlier security patch level on Qualcomm Snapdragon Mobile SD 835, SD 845, and SD 850, vendor specific opcodes may not have any packet length validation leading to buffer over-reads.
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.
