CVE-2019-11114

Vulnerability

Insufficient input validation in Intel(R) Driver & Support Assistant (DSA) version 19.3.12.3 and before allows a privileged user to potentially cause a denial of service. The vulnerability stems from improper handling of user-supplied input by the DSA application when performing certain operations with elevated privileges.

Exploitation

An attacker must have local access and possess valid privileged credentials (elevated privileges) on the system. With those privileges, the attacker can supply crafted input to the vulnerable component of Intel DSA, triggering the insufficient validation and leading to a denial of service condition.

Impact

Successful exploitation leads to a denial of service (DoS), causing the affected system to crash or become unavailable. The impact is limited to availability; the vulnerability does not allow code execution or privilege escalation beyond the attacker's existing privileged level.

Mitigation

Intel released an updated version of Intel Driver & Support Assistant (version 19.3.12.4 or later) to address this vulnerability. Users should update to the latest version available from Intel's official download site. No workarounds have been provided [1].
