|---|---|---|
| app center | < 19.0227.1 | 19.0227.1 |
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.
