11 Old Microsoft-Signed Linux UEFI Shims Could Let Attackers Bypass Secure Boot

Researchers discovered 11 Microsoft-signed UEFI applications that could allow attackers to bypass Secure Boot and execute arbitrary code during system boot. These vulnerable shims could be leveraged to deploy UEFI (Unified Extensible Firmware Interface) bootkits or other malware on affected systems.

Why it matters: Organizations running Linux on systems with Secure Boot enabled face firmware-level compromise risk; patching or removing these signed applications is critical to prevent bootkit deployment.
