    CVE-2026-20898 (GCVE-0-2026-20898)

    Vulnerability from nvd – Published: 2026-08-11 16:27 – Updated: 2026-08-12 14:48

    Summary
    Improper access control in the firmware for some in Alias Checking Trusted Module for some Intel(R) Xeon(R) processors may allow an escalation of privilege. Startup code and 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 not present without 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 (high), integrity (high) and availability (none) impacts.

    CVE-2026-20716 (GCVE-0-2026-20716)

    Vulnerability from nvd – Published: 2026-08-11 16:25 – Updated: 2026-08-12 15:50
    VLAI
    Summary
    Improper access control for some Intel(R) Processors within Ring 3: User Applications may allow an escalation of privilege. Simple hardware adversary with an authenticated 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.

    CVE-2026-20716 (GCVE-0-2026-20716)

    Vulnerability from cvelistv5 – Published: 2026-08-11 16:25 – Updated: 2026-08-12 15:50
    VLAI
    Summary
    Improper access control for some Intel(R) Processors within Ring 3: User Applications may allow an escalation of privilege. Simple hardware adversary with an authenticated 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.
    Severity
    7.2 (High)
