In all Qualcomm products with Android releases from CAF using the Linux kernel, there is no size check for the images being flashed onto the NAND memory in their respective partitions, so there is a possibility of writing beyond the intended partition.
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.
