CVE-2026-20734

Firmware Improper Initialization Leading to Local Information Disclosure in Intel AMT

Published Aug 11, 2026 CVSS 4.0 · 5.6 Medium EPSS < 1% KEV · Not listed
Description
Improper initialization in some firmware for some Intel(R) Active Management Technology (Intel(R) AMT), and some Intel(R) Standard Manageability may allow an information disclosure. System software adversary with a privileged user combined with a low complexity attack may enable data exposure. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (high), integrity (none) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
