CVE-2025-7027

8.2 · HIGH
Published Jul 11, 2025 EPSS 0.22% (13th pctl)

Overview

CVE-2025-7027 is a high-severity vulnerability. It was published on July 11, 2025 and has a CVSS 3.1 base score of 8.2 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.2, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

A vulnerability in the Software SMI handler (SwSmiInputValue 0xB2) allows a local attacker to control both the read and write addresses used by the CommandRcx1 function. The write target is derived from an unvalidated UEFI NVRAM variable (SetupXtuBufferAddress), while the write content is read from an attacker-controlled pointer based on the RBX register. This dual-pointer dereference enables arbitrary memory writes within System Management RAM (SMRAM), leading to potential SMM privilege escalation and firmware compromise.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
