No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

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. 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.
