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-787"],"vendors":[],"products":[],"references":[{"url":"https://github.com/NVIDIA/product-security/tree/main/2026/5861","tags":[]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47561","tags":[]},{"url":"https://www.cve.org/CVERecord?id=CVE-2026-47561","tags":[]}],"exploitRefs":[{"url":"https://github.com/NVIDIA/product-security/tree/main/2026/5861","tags":[]}],"hasPoc":true,"ai":{"summary":"The flaw is a buffer overflow vulnerability in the NVIDIA GPU Display Driver for Linux, which allows unprivileged users to execute arbitrary code or cause a denial of service. This matters because it can lead to significant security breaches, including code execution and privilege escalation.","exploitability":"Exploitation requires local access and knowledge of the specific ioctl command. The vulnerability is present in the kernel mode layer, making it potentially difficult to exploit without detailed understanding.","blast_radius":"If exploited, the vulnerability could result in code execution, denial of service, and escalation of privileges, impacting the security and stability of the affected system.","remediation":"Upgrade to the fixed version 535.30.03 or later.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["rce","privilege-escalation","kernel","local-privilege"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-10-08T08:42:05.074Z"}}
