CVE-2025-0221Public exploit

Local system crash via malformed driver IOCTL

Published Jan 5, 2025 · Updated Jan 6, 2025

Null pointer dereference in IObit Protected Folder 1.3.0 and earlier allows local users to crash Windows via a crafted driver IOCTL. The pffilter.sys handler for control code 0x22200c dereferences a null pointer while processing attacker-controlled IOCTL input. Low-privileged local access is sufficient; the published impact is a system crash with no reported data disclosure or modification.
