CVE-2020-12364: 
Linux Kernel vulnerability analysis and mitigation

A null pointer reference vulnerability (CVE-2020-12364) was identified in Intel Graphics Drivers for Windows before version 26.20.100.7212 and Linux kernel versions before 5.5. This vulnerability was disclosed and assigned on April 28, 2020, affecting Intel Graphics Driver systems on both Windows and Linux platforms (CVE MITRE).

The vulnerability is characterized as a null pointer reference issue in Intel Graphics Drivers. The vulnerability received a CVSS v3 severity score of 5.5 (Medium), indicating moderate severity (Ubuntu Security). The issue requires local access and privileged user permissions to be exploited.

If successfully exploited, this vulnerability could allow a privileged user to cause a denial of service condition through local access (NVD). The impact is limited to system availability and requires local access with elevated privileges to exploit.

The vulnerability requires local access and privileged user permissions to be exploited. This significantly reduces the risk as it cannot be exploited remotely and requires the attacker to already have elevated privileges on the target system (Red Hat Security).

The vulnerability was fixed through both firmware and kernel updates. For Windows systems, updating to Graphics Driver version 26.20.100.7212 or later resolves the issue. For Linux systems, updating to kernel version 5.5 or later, along with the corresponding firmware update v49.0.1, is required for complete mitigation (Debian Security).
