CVE-2023-1489Public exploit

Local kernel execution via unchecked MSR write

Published Mar 18, 2023 · Updated Aug 2, 2024

Improper access control in Wise System Monitor 1.5.3.54 allows local users to execute arbitrary code in the Windows kernel. The WiseHDInfo64.dll handler for IOCTL 0x9C402088 passes a user-controlled MSR index and value directly to __writemsr. Any normal local user able to open the driver device can write model-specific registers and gain kernel-level execution.
