CVE-2025-46713

Local code execution via pool allocation overflow

Published May 22, 2025 · Updated May 22, 2025

Buffer overflow in Sandboxie-Plus Sandboxie before 1.15.12 allows local users to execute arbitrary code through API_SET_SECURE_PARAM. Pool_Get_Large_Chunk adds alignment overhead to an attacker-controlled 32-bit size without detecting wraparound, allocates the resulting smaller buffer, and API_SET_SECURE_PARAM copies the original length into it. Low-privileged local access is required; successful exploitation targets kernel memory, although the vendor states that exploitability is unclear.
