4DescriptionCVE.org
Improper buffer restrictions for some Display Virtualization for Windows OS driver software within Ring 2: Device Drivers may allow a denial of service. Unprivileged software adversary with an authenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
AnalysisAI
Improper buffer restrictions in Intel's Display Virtualization for Windows OS driver software (Ring 2 device driver layer) allow a locally authenticated low-privileged user to trigger a denial of service condition affecting system availability. The flaw, tracked as CWE-119, resides in the driver's memory boundary enforcement and can be exploited without special internal knowledge or user interaction. No active exploitation has been identified (EPSS 0.01%, 3rd percentile; SSVC exploitation status: none), and the impact is limited to availability - confidentiality and integrity are unaffected.
Technical ContextAI
The vulnerability is rooted in CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer), commonly manifesting as buffer overflows or out-of-bounds reads/writes within the driver's processing logic. The affected component operates at Ring 2 - the device driver privilege ring - meaning the flaw exists within kernel-mode driver code on Windows that handles display virtualization. According to the CPE string (cpe:2.3:a:n/a:display_virtualization_for_windows_os_driver_software:*:*:*:*:*:*:*:*), the affected software is Intel's display virtualization driver suite for Windows, reported via Intel's own security advisory INTEL-SA-01430. Display virtualization drivers facilitate GPU sharing or virtual display output in environments such as virtualized desktop infrastructure (VDI). Buffer mishandling in such a driver can cause the operating system or the driver itself to crash, resulting in a denial of service.
RemediationAI
The primary remediation is to apply the updated driver version specified in Intel's security advisory INTEL-SA-01430, available at https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01430.html. The advisory should be consulted directly for exact patched version numbers, as no specific fix version is enumerated in the NVD or EUVD data available at time of analysis. If patching cannot be performed immediately, compensating controls include restricting local user access to systems running this driver (reducing the pool of low-privileged users who could trigger the flaw), or disabling the display virtualization driver component if it is not operationally required - though this may impact virtual display functionality in VDI or GPU-sharing deployments. Given the DoS-only impact and local-access requirement, the urgency for emergency patching is low for most environments; standard patch cycle scheduling is appropriate unless the environment is high-availability and local user access is broadly granted.
