CVE-2025-20031

Vulnerability

Overview

The vulnerability identified as CVE-2025-20031 stems from improper input validation within some Intel(R) Graphics Drivers. This flaw was disclosed in Intel's security advisory INTEL-SA-01259 [1]. The root cause is that the driver does not adequately validate certain inputs, which can be exploited to disrupt normal operation.

Exploitation

Conditions

An attacker must have authenticated access to the target system to exploit this vulnerability [1]. The attack vector is local, meaning the attacker needs a user account on the machine where the affected Intel Graphics Driver is installed. No special privileges beyond basic authentication are required, but the attacker must be able to execute code or trigger driver interaction locally.

Impact

Successful exploitation could lead to a denial of service (DoS) condition [1]. This means an attacker could cause the graphics driver to crash or become unresponsive, potentially affecting system stability and usability. The CVSS v3 base score of 6.5 (Medium) reflects the moderate severity of this local DoS risk.

Mitigation

Intel has released updates to address the issue, as detailed in their official advisory [1]. Users should update their Intel Graphics Drivers to the fixed versions specified in INTEL-SA-01259 to mitigate the vulnerability.
