What is CVE-2026-82017?
CVE-2026-82017 is a high-severity vulnerability in IGEL OS 11, published on 28 Aug 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
IGEL OS 12 before 12.7.6 and IGEL OS 11 before 11.11.150 contain a boot registry parameter injection vulnerability that allows attackers with physical access to execute arbitrary Linux loader parameters by writing to an unencrypted and unsigned configuration area read by the signed bootloader. Attackers can inject malicious kernel command line parameters that execute with boot environment privileges without triggering TPM PCR measurement failures, as the attack does not modify the measured boot code.
Weakness: CWE-345
