CVE-2026-92150 nasa CVE debrief
CVE-2026-92150 is a denial-of-service vulnerability in F´ (F Prime), a framework for developing and deploying spaceflight and other embedded software applications. The vulnerability occurs in the Svc::GenericHub fromBufferDriver_handler deserialization process, which uses FW_ASSERT for externally influenced deserialization status and type validation. This allows an unauthenticated inter-processor hub peer to send a truncated buffer, an invalid HubType, or a header-only command-dispatch payload, causing the process to abort or reset. The issue is fixed in version 4.2.0.

Who should care
Defenders responsible for F´ deployments, especially those using versions prior to 4.2.0, should assess their exposure and potential impact of denial-of-service attacks. Defenders should prioritize verifying exposure in F´ deployments and assess the impact of potential denial-of-service attacks on their systems, focusing on affected operator, platform, vulnerability-management, and security-team impact.
Why it matters
CVE-2026-92150 is a denial-of-service vulnerability in F´ that can be exploited by unauthenticated inter-processor hub peers. Defenders should prioritize verifying exposure and assessing potential impact on their systems.
- Denial of service through process abortion or reset
- Potential disruption of critical spaceflight or embedded systems
- Need for verification of F´ version and exposure
- Prioritization of upgrades to version 4.2.0 or later
Technical summary
The vulnerability occurs in the Svc::GenericHub fromBufferDriver_handler deserialization process, which uses FW_ASSERT for externally influenced deserialization status and type validation. This allows an unauthenticated inter-processor hub peer to send a truncated buffer, an invalid HubType, or a header-only command-dispatch payload, causing the process to abort or reset. The issue is fixed in version 4.2.0. Affected product deployments should be verified, and defenders should assess the impact of potential denial-of-service attacks on their systems.
Defensive priority
Defenders should prioritize verifying exposure in F´ deployments, especially those using versions prior to 4.2.0, and assess the impact of potential denial-of-service attacks on their systems.
Recommended defensive actions
- Verify F´ version and assess exposure
- Implement compensating controls to mitigate denial-of-service attacks
- Monitor system logs for potential exploitation attempts
- Upgrade to version 4.2.0 or later
- Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance
- Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
- Track exceptions, retest remediated assets, and close the item only after evidence is documented
Evidence notes
The CVE record and source item provide details on the vulnerability, its impact, and the fixed version. However, there is limited information on potential exploitation or victim impact. Defenders should verify F´ version and assess exposure, especially those using versions prior to 4.2.0. Limited source detail suggests explicit evidence-limit language and defensive verification tasks rather than invented vulnerability facts.
