CVE-2026-47506: CWE-121 Stack-based Buffer Overflow in NVIDIA GeForce
NVIDIA GPU Display Driver for Windows contains a vulnerability in the kernel-mode color transform path where excessive kernel stack use occurs when evaluating YCbCr420 display emulation. A successful exploit of this vulnerability might lead to denial of service.
AI Analysis
Technical Summary
This vulnerability involves a stack-based buffer overflow (CWE-121) in the NVIDIA GeForce GPU Display Driver for Windows. Specifically, excessive kernel stack usage occurs in the kernel-mode color transform path when processing YCbCr420 display emulation. The flaw can lead to denial of service conditions by crashing or destabilizing the system. The CVSS 3.1 base score is 5.5, reflecting local attack vector with low privileges required and no impact on confidentiality or integrity, only availability.
Potential Impact
Successful exploitation may cause denial of service by crashing or destabilizing the Windows system running the vulnerable NVIDIA GeForce driver. There is no indication of confidentiality or integrity compromise. No known exploits are reported in the wild.
Mitigation Recommendations
No vendor advisory or patch information is currently provided. Patch status is not yet confirmed — check the NVIDIA vendor advisory for current remediation guidance. Until a fix is available, limiting local access to trusted users may reduce risk.
