CVE-2020-28841Public exploit

Local system crash via crafted driver IOCTL

Published Jan 3, 2021 · Updated Aug 4, 2024

Denial of service in DriverGenius 9.61.3708.3054 allows local users to crash Windows via a crafted MyDrivers64.sys IOCTL request. The MyDrivers64.sys device handler accepts command 0x9c402000 on \.\MyDrivers0_0_1 and processes a crafted input buffer without adequate validation, triggering a kernel crash. Exploitation requires local code execution and the DriverGenius hardware-monitor driver to be loaded; the demonstrated consequence is a system crash only.
