CVE-2026-82017— IGEL OS 12 / 11 Boot Registry Parameter Injection via Unsigned Configuration Area

Quick assessment

Affected
IGEL IGEL OS 12
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

IGEL OS 12 早于 12.7.6 以及 IGEL OS 11 早于 11.11.150 的版本存在一个启动注册表参数注入漏洞。拥有物理访问权限的攻击者可以通过向由签名启动加载器读取的未加密且未签名的配置区域写入数据，从而执行任意的 Linux 加载器参数。攻击者可以注入恶意的内核命令行参数，使这些参数以启动环境权限执行，且不会触发 TPM PCR 度量失败，因为该攻击并未修改受度量的启动代码。

Vulnerability Title
IGEL OS 12 / 11 Boot Registry Parameter Injection via Unsigned Configuration Area
Source: CVE Program / CVE List V5
Vulnerability 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.
