Name of the Vulnerable Software and Affected Versions
Intel(R) Xeon(R) 6 processors (affected versions not specified)
Description
Improper handling of overlap between protected memory ranges occurs when using Intel(R) TDX (Trust Domain Extensions, a technology for hardware-isolated virtual machines) within SMM (System Management Mode, a highly privileged CPU operating mode). A local adversary with privileged user access and specialized internal knowledge may execute a high-complexity attack to achieve escalation of privilege. This issue impacts the confidentiality and integrity of the vulnerable system.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
