This series brings some missing validation for the IPI buffer size that is read from the firmware retrieved from userspace: if the FW declares IPI buffer offset starting at an out of range address, the driver doesn't do any validation and naively goes on with IO R/W operation.
That poses various risks which I believe I really don't need to describe, leaving it to the reader's imagination :-)
Please note that the first fix is URGENT.
P.S.: Of course, this was tested OK on multiple MTK platforms.
