This bug was found in msm-5.15 using tag KERNEL.PLATFORM.2.1.r1-05400-kernel.0. The fastrpc_file struct contains a flag, is_compat, that is set if the 32-bit compat_ioctl vfs handler is ever called on a fastrpc file (e.g. by opening and ioctling on /dev/adsprpc-smd). This flag is later used inside of e.g. fastrpc_internal_invoke2's macro invocations of K_COPY_FROM_USER to make decisions about whether the provided pointer is a userland pointer or a kernel-land pointer. However, because the state for making this K_COPY_FROM_USER decision is stored within the broadly accessible fastrpc_file struct instead of stored per ioctl invocation, this means that 64-bit ioctl invocations of fastrpc_internal_invoke2 will use userland provided addresses as kernel pointers if the 32-bit ioctl interface of the same fastrpc_file was ever previously invoked. This leads directly to attacker-controlled reads of arbitrary kernel addresses.
