CVE-2026-82670

Local privilege manipulation via driver IOCTL handling

Published Aug 31, 2026 · Updated Aug 31, 2026

Improper privilege management in IObit Uninstaller 15.5.0.11 allows local users to alter data and interrupt service via a driver IOCTL. The IUForceDelete.sys IRP_MJ_DEVICE_CONTROL handler processes an unspecified manipulated input, but the CNA has not disclosed the incorrect privilege operation or missing validation. Exploitation requires local low-privileged access, and the reported effects are limited integrity loss and service interruption without confidentiality impact.
