Technical details

A NULL pointer dereference (CWE-476) exists in the NASA core Flight System (cFS) Health and Safety (HS) application due to an incomplete fix for a previous vulnerability (CVE-2026-15352). The flaw is reachable via a specific command triggered under certain conditions. Successful exploitation allows an unauthenticated network attacker to crash the HS application, which triggers a processor reset and a denial-of-service condition. While an official release fix is under development, a patch is available in the project's development branch starting at commit 828855f.

Affected products

NASA core Flight System (cFS) Health and Safety (HS) Application <=v7.0.1
