Detailsinfo

A vulnerability classified as critical has been found in Ubuntu edk2 up to 2024.02-2ubuntu0.2/2024.05-2ubuntu0.2 on aarch64. This affects an unknown functionality. The manipulation with an unknown input leads to a debug code vulnerability. CWE is classifying the issue as CWE-489. The product is deployed to unauthorized actors with debugging code still enabled or active, which can create unintended entry points or expose sensitive information. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The Ubuntu edk2 UEFI firmware packages accidentally allowed the UEFI Shell to be accessed in Secure Boot environments, possibly allowing bypass of Secure Boot constraints. Versions 2024.05-2ubuntu0.3 and 2024.02-2ubuntu0.3 disable the Shell. Some previous versions inserted a secure-boot-based decision to continue running inside the Shell itself, which is believed to be sufficient to enforce Secure Boot restrictions. This is an additional repair on top of the incomplete fix for CVE-2023-48733.

The weakness was released by Dann Frazier. The advisory is shared at bugs.launchpad.net. This vulnerability is uniquely identified as CVE-2025-2486 since 03/18/2025. The exploitability is told to be difficult. An attack has to be approached locally. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 12/19/2025).

Upgrading to version 2024.02-2ubuntu0.3 or 2024.05-2ubuntu0.3 eliminates this vulnerability.
