Descriptions

NVIDIA DCGM contains a vulnerability in nvhostengine, where a network user can cause detection of error conditions without action, which may lead to limited code execution, some denial of service, escalation of privileges, and limited impacts to both data confidentiality and integrity.

NVIDIA DCGM contiene una vulnerabilidad en nvhostengine, donde un usuario de la red puede causar la detección de condiciones de error sin acción, lo que puede conllevar a una ejecución de código limitada, alguna denegación de servicio, escalada de privilegios e impactos limitados en la confidencialidad e integridad de los datos

NVIDIA DCGM runs on machines with NVIDIA GPUs to gather telemetry and GPU health data. nv-hostengine is a daemon that by default listens on the loopback interface, but can also listen on the network for requests coming in on port 5555 (remote mgmt). A native client named DCGMI allows users to make requests to the daemon to support a variety of functions. Malformed packets can cause the daemon (running as root or user account) to crash or potentially result in code execution. Versions less than 2.3.5 are affected.
