CVE-2023-1679Public exploit

Local privilege escalation via arbitrary physical-memory writes

Published Mar 28, 2023 · Updated Aug 2, 2024

Memory corruption in Driver-Soft Driver Genius 9.70.0.346 allows local users to gain kernel privileges through crafted driver IOCTLs. The mydrivers64.sys handlers for 0x9C406104 and 0x9C40A108 accept an attacker-controlled physical address and length, map that memory with MmMapIoSpace, and copy attacker data into it. A normal local user can invoke the exposed handlers to read or overwrite physical memory, enabling privilege escalation or kernel-code execution.
