CVE-2026-47491

Estado: Pendiente de análisisAlta (7.8)—

NVIDIA GPU Display Driver for Linux contains a vulnerability in the kernel mode layer where an unprivileged user can cause improper release of memory resources, leaving a mapping accessible after the underlying memory is reused. A successful exploit of this vulnerability might lead to code execution, denial of service, escalation of privileges, information disclosure, and data tampering.

CVSS

Versión: 3.1
