CVE-2025-25216 is a vulnerability identified in certain Intel Graphics Drivers and Intel Long-Term Support (LTS) kernels, specifically related to improper input validation within firmware components operating at Ring 1 privilege level (device drivers). This flaw allows an unprivileged but authenticated local user to trigger a denial of service (DoS) condition by supplying malformed inputs to the vulnerable driver firmware. The attack complexity is low, meaning it does not require advanced skills, but it does require local access and some specialized internal knowledge about the system's operation. No user interaction is needed once the attacker has authenticated access. The vulnerability does not compromise confidentiality or integrity, focusing solely on availability by causing system or driver crashes or hangs. The CVSS 4.0 vector indicates local attack vector (AV:L), low attack complexity (AC:L), privileges required (PR:L), no user interaction (UI:N), and low impact on availability (VA:L). No known exploits are currently reported in the wild, and no patches or affected version details are explicitly provided in the source data. The vulnerability was reserved in March 2025 and published in November 2025, indicating recent discovery and disclosure.

For European organizations, the primary impact of CVE-2025-25216 is a potential denial of service on systems running affected Intel Graphics Drivers and LTS kernels. This could lead to temporary system unavailability, potentially disrupting business operations, especially in environments relying on Intel-based hardware for critical workloads or graphical processing. Since the vulnerability requires local authenticated access, the risk is mitigated in well-segmented and access-controlled environments. However, organizations with many users having local access or with weak internal access controls could face increased risk. The lack of confidentiality or integrity impact reduces the risk of data breaches or system compromise. Still, availability disruptions could affect service continuity, particularly in sectors like finance, manufacturing, or public services where uptime is critical. The absence of known exploits reduces immediate threat but does not eliminate future risk once exploit code becomes available.

To mitigate CVE-2025-25216, European organizations should: 1) Apply any available patches or firmware updates from Intel promptly once released, as the vulnerability involves device driver firmware. 2) Restrict local access to systems with affected Intel Graphics Drivers and LTS kernels to trusted and authenticated users only, minimizing exposure. 3) Implement strict access control policies and monitor for unusual local activity that could indicate exploitation attempts. 4) Employ endpoint detection and response (EDR) solutions capable of detecting driver crashes or unusual device behavior. 5) Maintain up-to-date inventories of hardware and software to quickly identify affected systems. 6) Consider isolating critical systems or using virtualization/containerization to limit the impact of potential DoS conditions. 7) Educate users about the importance of not running untrusted code locally and maintaining good security hygiene. These steps go beyond generic advice by focusing on local access control, monitoring, and proactive patch management specific to Intel driver firmware vulnerabilities.
