Go to dashboardIGEL OS, the thin-client operating system, has a flaw where an expired signing key is still accepted, letting an attacker bypass Secure Boot. A crafted root filesystem image can then be mounted without verification, which means attacker-controlled code can run during boot.

Unknown from the sources.
Each row is the first time that source carried this signal. The analyst’s rows are its own findings.
IGEL OS contains a use of a key past its expiration date vulnerability that allows for Secure Boot bypass. The igel-flash-driver module improperly verifies a cryptographic signature. Ultimately, a crafted root filesystem can be mounted from an unverified SquashFS image.
CISA required action: Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
