Technical details
The vulnerability exists in the sandbox provisioning API of NVIDIA OpenShell for Linux, where an incomplete allowlist of disallowed inputs permits an attacker to supply malicious or unexpected values that circumvent input validation controls. This input validation weakness is network-accessible and can be exploited without requiring prior authentication or special privileges. A successful exploit enables code execution at elevated privilege levels, information disclosure, tampering with system data, and denial of service. NVIDIA has issued a fix; affected users should upgrade to the patched version immediately.
