Description

Trusty TLK contains a vulnerability in the NVIDIA TLK kernel function where a lack of checks allows the exploitation of an integer overflow on the size parameter of the tz_map_shared_mem function, which might lead to denial of service, information disclosure, or data tampering.

• CWE-190Integer Overflow or WraparoundThe 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.
