Description

CVE-2026-18064 is a NULL pointer dereference vulnerability in the NASA Core Flight System (cFS) Health & Safety (HS) application. It results from an incomplete fix for a previous vulnerability (CVE-2026-15352) and affects versions up to and including 7.0.1. An attacker able to trigger a specific command under certain conditions could cause the HS application to crash, leading to a denial-of-service and processor reset.

Technical Analysis

This vulnerability is a NULL pointer dereference in the NASA cFS HS application caused by an incomplete remediation of CVE-2026-15352. The flaw is reachable in versions through 7.0.1. Exploitation requires triggering a specific command under particular conditions, causing the application to crash and the processor to reset, resulting in denial of service. The CVSS 3.1 base score is 7.5, indicating high severity, with network attack vector, low attack complexity, no privileges or user interaction required, and impact limited to availability.

Potential Impact

Successful exploitation causes the HS application to crash and triggers a processor reset, resulting in denial-of-service conditions. There is no impact on confidentiality or integrity reported. This could disrupt system operations relying on the HS application.

Mitigation Recommendations

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch has been documented at this time. Until a fix is available, avoid triggering the affected command under the specific conditions that lead to the NULL pointer dereference.
