CVE-2025-35991

Improper Initialization in UEFI Firmware Enables Information Disclosure on Intel Platforms

Published May 12, 2026 CVSS 4.0 · 5.6 Medium EPSS < 1% KEV · Not listed
Description
Improper initialization in the UEFI firmware for some Intel platforms within Ring 0: Bare Metal OS may allow an information disclosure. System software adversary with a privileged user combined with a high 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.
