vfio/platform: check the bounds of read/write syscalls
commit ce9ff21ea89d191e477a02ad7eabf4f996b80a69 upstream.
count and offset are passed from user space and not checked, only
offset is capped to 40 bits, which can be used to read/write out of
bounds of the device.
Fixes: 6e3f26456009 (“vfio/platform: read and write support for the device fd”)
