In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_ffa: Check if ffa_driver remove is present before executing
Currently ffa_drv->remove() is called unconditionally from ffa_device_remove(). Since the driver registration doesn't check for it and allows it to be registered without .remove callback, we need to check for the presence of it before executing it from ffa_device_remove() to above a NULL pointer dereference like the one below:
