CVE-2025-46714Public exploit

Kernel crash via integer-wrapped pool allocation

Published May 22, 2025 · Updated May 22, 2025

Pool buffer overflow in Sandboxie 1.3.0 through 1.15.11 allows local users to crash Windows or execute code in the kernel. The SbieDrv.sys API_GET_SECURE_PARAM handler stores a WCHAR name length in a 32-bit ULONG; a huge caller-controlled name wraps the allocation size before wcscpy copies the full string into the undersized pool buffer. Low-integrity processes can reach the driver API, and the proof of concept triggers a PAGE_FAULT_IN_NONPAGED_AREA crash; arbitrary code execution is identified as the worst case, but its exploitability remains unresolved.
