CVE-2018-12211

Vulnerability

Insufficient input validation in the User Mode Driver component of Intel Graphics Driver for Windows before versions 10.18.x.5059 (aka 15.33.x.5059), 10.18.x.5057 (aka 15.36.x.5057), 20.19.x.5063 (aka 15.40.x.5063), 21.20.x.5064 (aka 15.45.x.5064), and 24.20.100.6373 allows an unprivileged user to cause a denial of service via local access [1].

Exploitation

An attacker with local access to the system can exploit this vulnerability by providing specially crafted input to the User Mode Driver. No authentication or elevated privileges are required beyond local user access. The attacker would need to execute a program that interacts with the graphics driver in a way that triggers the insufficient input validation [1].

Impact

Successful exploitation leads to a denial of service, causing the system or graphics subsystem to become unresponsive or crash. The attacker does not gain code execution or privilege escalation; the impact is limited to availability [1].

Mitigation

Intel released fixed driver versions: 10.18.x.5059, 10.18.x.5057, 20.19.x.5063, 21.20.x.5064, and 24.20.100.6373. Users should update to these or later versions via Intel's driver update tools or Windows Update. No workaround is provided; updating is the recommended mitigation [1].
