Description

NVIDIA DGX A100 contains a vulnerability in SBIOS in the SmmCore, where a user with high privileges can chain another vulnerability to this vulnerability, causing an integer overflow, possibly leading to code execution, escalation of privileges, denial of service, compromised integrity, and information disclosure.

• 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.
