CVE-2026-92155: F Prime FilePacket deserialization denial of service

CVE-2026-92155 · Severity: high · CVSS 7.5 · Published 2026-10-14

F´ (F Prime) is a framework used for spaceflight and embedded software applications. A flaw in how it processes file upload packets allows an attacker on the network to send a specially crafted packet that triggers an assertion failure, crashing or resetting the application and causing a denial of service.

Technologies: Nasa F Prime. Vendors: Nasa.

How to fix

Fixed in: 4.2.0

Technical details

The vulnerability exists in Fw::FilePacket deserialization used by Svc::FileUplink, where the type byte in the file packet header is cast to an enum without range validation. When an invalid type byte is received, the code reaches a FW_ASSERT that aborts the process rather than gracefully handling the error. An attacker with network access can send a file packet with an unknown type byte to trigger the denial of service.

Affected products

NASA F Prime prior to 4.2.0
