CyberRota Analysis
AI-GeneratedThe vulnerability arises from the Direct XIP update strategy, where the main application image can initiate other cores without proper verification, potentially leading to the execution of unauthorized code. This flaw allows MCUboot to boot from different slots for various images, which could compromise the integrity of the system by executing a radio image from an unauthenticated slot. Organizations utilizing affected products with MCUboot should prioritize addressing this vulnerability to mitigate risks of unauthorized access and control over their systems.
Original NVD Description
When using the Direct XIP update strategy, the main application image starts other cores (i.e. radio core), based on the currently active slot without additional verification. The MCUboot in the bare (upstream) configuration assumes that if there is at least a single slot for each image available, the system is bootable and continues the boot process. This may lead to a situation when MCUboot picks different slot for different images (i.e. (a) for the main application and (b) for the radio image), boots the main application (from slot (a)) that afterwards starts the radio image by providing an address of the unauthenticated slot ((a) instead of (b)).
