CVE-2026-92159 Details
Description
F´ (F Prime) is a framework that enables development and deployment of spaceflight and other embedded software applications. Prior to 4.3.0, Svc::TlmPacketizer TlmRecv_handler fixed-slot copy TlmRecv_handler copies val.getSize bytes into entry.channelSize storage without confirming that the runtime value fits. When a telemetry update for a configured channel carries a serialized value larger than that channel fixed slot, the copy overwrites adjacent channel fields and causes corrupted packetized telemetry to be emitted. This issue is fixed in version 4.3.0.
A vulnerability exists in the NASA F' framework's telemetry packet handling component, specifically in versions through 4.2.1. The issue arises in the 'Svc::TlmPacketizer' class, where the 'TlmRecv_handler' function copies telemetry data into fixed-size channel slots without verifying that the data fits. This oversight can lead to larger-than-expected values overwriting adjacent channel information, causing corruption in the final emitted telemetry packets. The flaw can be exploited by sending oversized telemetry updates through the 'GenericHub' component, which bridges different address spaces and forwards the data to 'TlmPacketizer'. As a result, packet consumers may receive distorted information that does not align with the intended telemetry values or the configured packet structure.
Users can update to F' version 4.3.0 or later, where this vulnerability has been fixed.
