A malformed firmware patch shorter than the version field\ncan make this subtraction underflow and turn the copy into an oversized\nread and write during Bluetooth setup.\n\nThe existing patch_offset + patch_length check can also wrap on 32-bit\narchitectures. Validate the patch length and range without arithmetic\noverflow before allocating or copying the patch.",
