Name of the Vulnerable Software and Affected Versions
Cheetah free WiFi version 5.1
Description
The issue allows local users to cause a denial of service (BSOD) or possibly have unspecified other impact. This is due to the driver file (liebaonat.sys) not validating input values from IOCtl
0x830020f8, 0x830020E0, 0x830020E4, or 0x8300210c.Recommendations
For Cheetah free WiFi version 5.1, consider disabling the liebaonat.sys driver file as a temporary workaround to minimize the risk of exploitation. Restrict access to the IOCtl codes
0x830020f8, 0x830020E0, 0x830020E4, and 0x8300210c to prevent potential denial of service attacks. At the moment, there is no information about a newer version that contains a fix for this issue.Exploit
