A successful exploit of this vulnerability might lead to code execution, denial of service, escalation of privileges, information disclosure, and data tampering.","cvssScore":7.8,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","cwes":["CWE-190"],"vendors":[],"products":[],"references":[{"url":"https://github.com/NVIDIA/product-security/tree/main/2026/5861","tags":[]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47556","tags":[]},{"url":"https://www.cve.org/CVERecord?id=CVE-2026-47556","tags":[]}],"exploitRefs":[{"url":"https://github.com/NVIDIA/product-security/tree/main/2026/5861","tags":[]}],"hasPoc":true,"ai":{"summary":"The flaw is an integer overflow in the NVIDIA GPU Display Driver that can lead to out-of-bounds writes, potentially allowing unprivileged users to execute code, cause a denial of service, escalate privileges, disclose information, and tamper with data. This matters because it significantly impacts system security and stability.","exploitability":"Exploitation requires local user privileges and could be moderately difficult due to the need to trigger the integer overflow condition. Precondition is the presence of the vulnerable NVIDIA driver version.","blast_radius":"If exploited, this vulnerability could lead to complete system compromise, including code execution, data loss, and unauthorized access, affecting both Windows and Linux systems.","remediation":"Upgrade to the fixed version 535.86 or later.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["rce","priv-escalation","data-tampering","info-disclosure","local-privilege","gpu"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-10-08T08:42:08.191Z"}}
