CVE-2026-47556

A flaw was found in the NVIDIA GPU display driver. A local unprivileged user can trigger an integer overflow in the driver's kernel mode layer, leading to an out-of-bounds memory write. Successful exploitation could allow an attacker to execute arbitrary code, escalate privileges, cause a denial of service (DoS), or tamper with sensitive data.

This vulnerability is rated as Important because an authenticated local user could leverage integer handling flaws in the kernel module to perform out-of-bounds writes, potentially resulting in elevated privileges or host compromise. Exposure is limited to environments where NVIDIA hardware is deployed and the proprietary kernel-mode driver is loaded. Red Hat Enterprise Linux releases are not affected because the vulnerable code base is not present in supported driver packages.
