Core Flight System Cfs Health Safety Hs Application
Monthly
Denial-of-service in the NASA core Flight System (cFS) Health and Safety (HS) application affects versions through 7.0.1, where a NULL pointer dereference left reachable by an incomplete fix for CVE-2026-15352 lets an attacker who can deliver a specific HS command under particular conditions crash the HS application and force a processor reset. The flaw impacts availability only - no confidentiality or integrity loss - and there is no public exploit identified at time of analysis, though it was reported through CISA ICS-CERT (advisory ICSA-26-211-06). Because cFS runs as the flight software framework aboard spacecraft and embedded aerospace systems, a triggered reset can disrupt mission-critical monitoring rather than expose data.
Denial of service in NASA's Core Flight System (cFS) Health & Safety (HS) application allows a remote attacker to crash the application through a NULL pointer dereference triggered while processing a routine Housekeeping Telemetry request. All HS versions prior to v7.0.1 are affected; the crash produces a segmentation fault that halts the health-monitoring task. No public exploit identified at time of analysis, and it is not listed in CISA KEV, but a CISA ICS advisory (ICSA-26-197-03) and vendor-tagged fix release exist.
