Trusty TLK contains a vulnerability in the NVIDIA TLK kernel where an integer overflow in the tz_map_shared_mem function can bypass boundary checks, which might lead to denial of service.
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
