Описание
Improper handling of overlap between protected memory ranges for some Intel(R) Xeon(R) 6 processors when using Intel(R) TDX within SMM may allow an escalation of privilege. SMM adversary with a privileged user combined with a high complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are present with special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (high), integrity (high) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
A flaw was found in Intel(R) Xeon(R) 6 processors when using Intel(R) TDX within System Management Mode (SMM). Improper handling of overlap between protected memory ranges may allow a local attacker with privileged user access to escalate privileges. This vulnerability could lead to high impact on confidentiality and integrity of the system.
Отчет
This Important privilege escalation flaw affects Intel Xeon 6 Processors when Intel TDX is enabled, allowing a privileged local attacker to escalate privileges within the System Management Mode (SMM). Exploitation requires a high complexity attack and specific internal knowledge, impacting the confidentiality and integrity of the system.
Меры по смягчению последствий
This vulnerability only affects systems using Intel Trust Domain Extensions (TDX) on Intel Xeon 6 processors. Systems not using Intel TDX are not vulnerable to this issue. Disabling Intel TDX, where feasible, removes the exposure to this vulnerability.
