Impact

NVIDIA GPU Display Driver for Windows and Linux contains a flaw in the kernel-mode component that allows a local user to trigger the driver to copy kernel memory that has not been properly initialized back into user space. This results in unintended exposure of kernel data such as internal structure contents, which can reveal sensitive information about the system state. The CVSS score of 5.5 indicates moderate severity: the vulnerability does not grant arbitrary code execution and is confined to information disclosure.

Affected Systems

All NVIDIA graphics products that rely on the affected driver, including GeForce, RTX, Quadro, NVS, Tesla, the Guest Driver, and the Virtual GPU Manager. Exact version numbers are not listed in the advisory, so any installation that has not yet applied the latest driver update remains vulnerable.

Risk and Exploitability

The impact hinges on the ability to load the vulnerable driver, which typically requires administrative privileges or local user control over driver installation. Because the exploit relies on an uninitialized memory copy, it does not require complex inputs and could be triggered by a simple driver call. The EPSS metric is not reported, and the vulnerability is not in CISA's KEV catalog, suggesting limited public exploitation data. Nonetheless, the CVSS score reflects that a successful exploitation would compromise confidentiality but not integrity or availability.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade to the latest NVIDIA driver version that includes the fix for CVE-2026‑47555.
  • If a patched driver is not yet available, restrict kernel driver loading rights so that only highly trusted administrators can load drivers, minimizing risk of exploitation.
  • Apply system hardening: enforce SELinux, AppArmor, or equivalent policy to limit access to kernel memory and block uninitialized memory reads from user space.
