CVE-2026-82017Public exploit

Physical code execution via unsigned boot configuration

Published Aug 28, 2026 · Updated Aug 28, 2026

Boot registry parameter injection in IGEL OS 11 before 11.11.150 and IGEL OS 12 before 12.7.6 allows physically proximate attackers to execute code. The signed bootloader reads Linux loader parameters from an unencrypted, unsigned Boot Registry area without authenticating its contents. Physical access to the device and a reboot are required; injected kernel command-line parameters run with boot-environment privileges while measured boot code remains unchanged.
