CVE-2026-92154 Details
Description
F´ (F Prime) is a framework that enables development and deployment of spaceflight and other embedded software applications. Prior to 4.2.0, Svc::FileUplink handleDataPacket offset and size validation is vulnerable because the component checks byteOffset plus dataSize with wrapping U32 arithmetic and then seeks to the large attacker-controlled offset before writing. When a file-uplink DATA packet supplies a byteOffset and dataSize whose unsigned sum wraps below the declared file size, data can be written beyond the declared upload size, causing file integrity loss and potentially large sparse-file growth or resource exhaustion. This issue is fixed in version 4.2.0.
A vulnerability exists in the NASA F' framework's file uplink service, specifically in versions prior to 4.2.0. The issue arises in the offset and size validation of data packets, where the component improperly checks the byte offset and data size using wrapping arithmetic. This flaw allows an attacker to manipulate the offset and write data beyond the declared file size, leading to potential file corruption, integrity loss, and excessive storage consumption. The vulnerability is caused by inadequate bounds checking in the file uplink data packet handling, allowing for unauthorized writes at controlled offsets.
Users can update to F' version 4.2.0 or later, where this vulnerability has been fixed.
