Description

NVIDIA DGX A100 SBIOS contains a vulnerability where a local attacker can cause input validation checks to be bypassed by causing an integer overflow. A successful exploit of this vulnerability may lead to denial of service, information disclosure, and 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.
