Improper access control in Intel Graphics Driver for Windows - CVE-2019-0154

Vulnerability identifier: #VU22743

CSH Severity: Low

CVSS v4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2019-0154

CWE-ID: CWE-284

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local user to gain unauthorized access to otherwise restricted functionality.

The vulnerability exists due to improper access restrictions. A local user with the ability to issue an ioctl can trigger a hardware level crash if MMIO registers were read while the graphics card was in a low-power state and cause a denial of service (DoS) on the target system.
