    Kernel: Prevent out-of-bounds read/write in VirtIO GPU3DDevice::ioctl
    
    Before doing a check if offset_in_region + num_bytes of the transfer
    descriptor are together more than NUM_TRANSFER_REGION_PAGES * PAGE_SIZE,
    check that addition of both of these parameters will not simply overflow
    which could lead to out-of-bounds read/write.
    
    Fixes #17518.
