CVE-2019-7244

An issue was discovered in kerneld.sys in AIDA64 before 5.99. The vulnerable driver exposes a wrmsr instruction via IOCTL 0x80112084 and does not properly filter the 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 kerneld.sys en AIDA64 versiones anteriores a 5.99. El controlador vulnerable expone una instrucción wrmsr por medio de una IOCTL 0x80112084 y no filtra correctamente el Model Specific Register (MSR). Permitiendo escrituras arbitrarias del MSR puede conllevar a una ejecución de código Ring-0 y a una escalada de privilegios.
