CVE-2026-18064 NASA CVE debrief

Who should care

Organizations using the NASA core Flight System (cFS) Health and Safety (HS) application, particularly those in critical infrastructure or with high-availability requirements, should verify their inventory and assess the potential impact of this vulnerability. They should also monitor for patches or updates from NASA and consider compensating controls for exposed systems while remediation is scheduled and verified. Additionally, they should review relevant monitoring, detection, and logs for exposed assets that need extra review and track exceptions, retest remediated assets, and close the item only after evidence is documented. The vulnerability management and security teams should prioritize this vulnerability based on the potential operational impact and source-confidence limits. The affected operator and platform should also be considered when assessing the potential impact of this vulnerability. The security teams should review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance. They should plan vendor-supported updates or mitigations through normal change control where exposure is confirmed. The asset inventory and rollback/change windows should also be reviewed to ensure that the necessary steps are taken to mitigate the vulnerability. The source tracking and compensating controls should be implemented to minimize the potential impact of this vulnerability. The monitoring and detection capabilities should be reviewed to ensure that they can detect potential exploitation attempts. The security teams should also review the CVE record and NVD detail to validate the affected scope and severity of this vulnerability. The official CVE record and NVD detail provide additional information on the vulnerability and its potential impact. The security teams should use this information to prioritize their vulnerability management efforts and ensure that the necessary steps are taken to mitigate the vulnerability. The CVE record and NVD detail should be used to validate the affected scope and severity of this vulnerability and to prioritize vulnerability management efforts. The security teams should also review the CV

Technical summary

The NASA core Flight System (cFS) Health and Safety (HS) application is vulnerable to a denial-of-service condition due to a NULL pointer dereference. An attacker who can trigger the affected command under specific conditions could cause the HS application to crash, resulting in a denial-of-service condition and processor reset. This vulnerability affects versions through 7.0.1, and defenders should assess the potential impact on their systems.

Defensive priority

Organizations using the NASA core Flight System (cFS) Health and Safety (HS) application should verify their inventory and assess the potential impact of this vulnerability.

Recommended defensive actions

• Verify inventory of NASA core Flight System (cFS) Health and Safety (HS) application versions through 7.0.1
• Assess potential impact of NULL pointer dereference vulnerability
• Monitor for patches or updates from NASA
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed

Evidence notes

The CVE description indicates an incomplete fix for CVE-2026-15352 in the NASA core Flight System (cFS) Health and Safety (HS) application leaves a separate NULL pointer dereference reachable in versions through 7.0.1. The source details are limited, and defenders should verify the affected scope and potential impact based on available information.
