0 CVE-2025-2486 is a low-severity vulnerability in Ubuntu's edk2 UEFI firmware packages that allowed unintended access to the UEFI Shell in Secure Boot environments, potentially bypassing Secure Boot restrictions. The issue stems from active debug code that permitted the UEFI Shell to run despite Secure Boot protections. Versions 2024.05-2ubuntu0.3 and 2024.02-2ubuntu0.3 disable the Shell to mitigate this risk. This vulnerability builds on an incomplete fix for CVE-2023-48733. Exploitation requires local access and user interaction, with high attack complexity and no known exploits in the wild. The vulnerability primarily affects systems running Ubuntu with affected edk2 versions, and its impact on confidentiality, integrity, and availability is limited due to the constraints on exploitation.
