Descriptions

An issue was discovered in gdrv.sys in Gigabyte APP Center before 19.0227.1. The vulnerable driver exposes a wrmsr instruction via IOCTL 0xC3502580 and does not properly filter the target Model Specific Register (MSR). Allowing arbitrary MSR writes can lead to Ring-0 code execution and escalation of privileges.

Se detectó un problema en la biblioteca gdrv.sys en Gigabyte APP Center versiones anteriores a 19.0227.1. El controlador vulnerable expone una instrucción wrmsr por medio de una IOCTL 0xC3502580 y no filtra apropiadamente el Model Specific Register (MSR) objetivo. Permitiendo escrituras arbitrarias del MSR puede conllevar a una ejecución de código Ring-0 y a una escalada de privilegios.
