CVE-2019-15661Public exploit

Kernel code execution via unchecked IOCTL parameters

Published Mar 20, 2020 · Updated Aug 5, 2024

Stack-based buffer overflow in Rivet Killer Control Center before 2.1.1352 allows local users to execute kernel code via a driver IOCTL. KfeCo10X64.sys processes IOCTL 0x120004 without validating caller-supplied parameters, allowing an oversized input buffer to overwrite stack memory. The attacker must execute code on the Windows host and open the driver's device; successful exploitation grants code execution or elevated privileges.
