In all Qualcomm products with Android releases from CAF using the Linux kernel, using a debugfs node, a write to a PCIe register can cause corruption of kernel memory.
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.
