CVE-2025-0285

Local SYSTEM escalation via unchecked IOCTL length

Published Mar 3, 2025 · Updated Sep 9, 2025

Arbitrary kernel memory mapping in Paragon Software products allows local users to gain SYSTEM privileges through BioNTdrv.sys. IOCTL 0x220014 accepts a user-supplied length without adequate validation, allowing attacker-controlled kernel memory mappings. A low-privileged local user with access to the device interface can elevate to SYSTEM; the flaw provides no remote attack path.
