Name of the Vulnerable Software and Affected Versions
The product name cannot be determined (affected versions not specified)
Description
A System Management Mode (SMM) handler—a high-privilege operating mode in x86 CPUs used for low-level hardware control—could perform a callout to code located in non-SMM or untrusted memory. A highly privileged attacker could trigger the execution of attacker-controlled code within the SMM, which may compromise the system's confidentiality, integrity, and availability. This requires active user interaction, high complexity, and specific preconditions.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
