Iwona Winiarska 01e6c64bbc soc: aspeed: p2a-ctrl: Fix boundary check for mmap ... commit 8b07e990fb254fcbaa919616ac77f981cb48c73d upstream. The check mixes pages (vm_pgoff) with bytes (vm_start, vm_end) on one side of the comparison, and uses resource address (rather than just the resource size) on the other side of the comparison. This can allow malicious userspace to easily bypass the boundary check and map pages that are located outside memory-region reserved by the driver.
