CVE-2026-47561

Estado: Pendiente de análisisAlta (7.8)—

NVIDIA GPU Display Driver for Linux contains a vulnerability in the kernel mode layer where the size of an ioctl input buffer is not validated, allowing an unprivileged caller to trigger an out-of-bounds write in kernel memory. A successful exploit of this vulnerability might lead to code execution, denial of service, escalation of privileges, information disclosure, and data tampering.

CVSS
