CVE-2026-47561

A flaw was found in the NVIDIA GPU display driver. A local, unprivileged user can exploit this vulnerability by submitting an input/output control (ioctl) request with an unvalidated buffer size to the driver's kernel layer. This causes an out-of-bounds write in kernel memory, which may allow the attacker to execute arbitrary code with elevated privileges, crash the system leading to a Denial of Service (DoS), or tamper with sensitive data.
