UEFI Shell accessible in AAVMF with Secure Boot enabled on Ubuntu
CVE-2025-2486 is fixed in 13 products on 1 platform, first by efi-shell-aa64 2025.02-3ubuntu1, released April 28, 2025. It is not reported as exploited. Patch Radar priority: High.
The Ubuntu edk2 UEFI firmware packages accidentally allowed the UEFI Shellto be accessed in Secure Boot environments, possibly allowing bypass ofSecure Boot constraints. Versions 2024.05-2ubuntu0.3 and 2024.02-2ubuntu0.3disable the Shell. Some previous versions inserted a secure-boot-baseddecision to continue running inside the Shell itself, which is believed tobe sufficient to enforce Secure Boot restrictions. This is an additionalrepair on top of the incomplete fix for CVE-2023-48733.
