Name of the Vulnerable Software and Affected Versions NVIDIA vGPU software versions prior to 12.3 NVIDIA vGPU software versions prior to 11.5 NVIDIA vGPU software versions prior to 8.8

Description The Virtual GPU Manager (vGPU plugin) in NVIDIA vGPU software contains a flaw where it improperly validates the length field in a request from a guest. This allows a malicious guest to send a length field that is inconsistent with the actual length of the input, potentially leading to information disclosure, data tampering, or denial of service.
