Description

Trusty contains a vulnerability in the NVIDIA TLK kernel function where a lack of checks allows the exploitation of an integer overflow through a specific SMC call that is triggered by the user, which may lead to denial of service.

• 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.
