Details

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.

Severity

7.5 (High)
