Summary The NPU device’s kernel driver implements a set of ioctl handlers one of which uses unsanitized user data as an index into a function pointer array. The user provided values can exceed the boundaries of the legitimate array and might cause user controlled values to be called as function pointers. A malicious actor can use this vulnerability to hijack the control flow of the kernel and call arbitrary functions with controlled parameters. The function pointer callsite is protected by clang’s CFI, which reduces the number of function that can be called through this primitive. The mmap handler is exposed through the /dev/davinci0 character device.
