CVE-2026-92151 nasa CVE debrief

Who should care

Defenders responsible for F´ deployments, especially those handling CCSDS telecommand frames, should assess exposure and prioritize upgrading to version 4.2.0 or later. This includes reviewing and updating defensive configurations for handling CCSDS telecommand frames, monitoring system logs for potential denial-of-service events, and performing vulnerability scanning to identify potential exposure. Additionally, defenders should review asset inventory for

Why it matters

A denial-of-service vulnerability in F´ framework versions prior to 4.2.0 requires attention from defenders responsible for F´ deployments, especially those handling CCSDS telecommand frames.

• Potential denial-of-service events require verification and monitoring
• Defensive configurations for handling CCSDS telecommand frames need review and update
• Upgrade to version 4.2.0 or later is necessary to fix the vulnerability

Technical summary

The Svc::Ccsds::SpacePacketDeframer dataIn_handler in F´ (F Prime) framework versions prior to 4.2.0 is vulnerable to denial-of-service attacks due to an assertion that aborts or resets the flight-software process when processing CCSDS telecommand frames with small payloads. The vulnerability is caused by the handler treating the minimum packet-length condition as FW_ASSERT rather than rejecting and returning the buffer. This issue can be triggered when a CCSDS telecommand frame with a payload of six bytes or fewer is processed. The fix in version 4.2.0 addresses this issue by properly handling the minimum packet-length condition.

Defensive priority

Defenders should prioritize verifying exposure in F´ deployments, especially those handling CCSDS telecommand frames, and upgrade to version 4.2.0 or later.

Recommended defensive actions

• Verify F´ version and upgrade to 4.2.0 or later if necessary
• Review and update defensive configurations for handling CCSDS telecommand frames
• Monitor system logs for potential denial-of-service events
• Perform vulnerability scanning to identify potential exposure
• Review asset inventory for affected systems
• Implement compensating controls for exposed systems
• Track exceptions and retest remediated assets

Evidence notes

The CVE record and source item provide details on the vulnerability, its impact, and the fix in version 4.2.0. However, additional information on potential exploitation or affected systems is limited.
