Nvidia Warns Windows Gamers on GPU Driver Flaws

Nvidia Warns Windows Gamers on GPU Driver Flaws (Malware and Vulnerabilities)

Nvidia has patched three vulnerabilities in its Windows GPU display driver that could enable information disclosure, denial of service and privilege escalation. Graphics chipmaker Nvidia has issued three patches for high-severity vulnerabilities in its GPU display driver, which could lead to information disclosure, escalation of privileges and denial of service (DoS) in impacted Windows gaming devices. The most severe of the flaws, CVE‑2019‑5675, could be exploited to launch DoS attacks that could cripple the system, as well as give attackers escalation of privileges and disclose system information, according to a Thursday advisory released by Nvidia. Kernel mode is generally reserved for the lowest-level, most trusted functions of the operating system; in this case, the layer handler for the DxgkDdiEscape interface within the kernel mode does not properly synchronize shared data, which could lead to glitches in the behavior of the data – resulting in malicious attacks, according to Nvidia’s security release, issued Thursday.
