This vulnerability (CVE-2026-47509) affects the NVIDIA GeForce GPU Display Driver on Windows and Linux platforms. It is caused by an out-of-bounds write in the kernel mode layer, which could allow a user with high privileges to execute arbitrary code, cause denial of service, escalate privileges, disclose information, or tamper with data. The CVSS v3.1 base score is 6.7 with vector AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H, reflecting local attack vector, low attack complexity, high privileges required, no user interaction, unchanged scope, and high impact on confidentiality, integrity, and availability. There is no vendor advisory or patch information available in the provided data.

If exploited, this vulnerability could allow an attacker with high privileges on the system to execute arbitrary code in kernel mode, cause system crashes (denial of service), escalate privileges further, disclose sensitive information, and tamper with data. The impact affects confidentiality, integrity, and availability of the affected system.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch information is provided in the available data. Until a patch is available, limit access to systems with NVIDIA GeForce drivers to trusted users with high privileges to reduce risk.
