Summary

CVE-2026-15352 is a high-severity NULL Pointer Dereference (CWE-476) vulnerability in Cisa (inferred from references). Its CVSS base score is 8.2 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Application or System Exploitation (T1499.004); ranked at the 35th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) and SI-2 (Flaw Remediation) — see the control section below for these in your framework.

Vulnerability Data

A vulnerability exists in the Health & Safety (HS) application of NASA's Core Flight System (cFS). The flaw allows the application to crash via segmentation fault when processing a routine Housekeeping Telemetry request, leading to denial of service.

MITRE ATT&CK Enterprise TechniquesAI

T1499.004 Application or System Exploitation Impact
Adversaries may exploit software vulnerabilities that can cause an application or system to crash and deny availability to users.
Why these techniques?

NULL pointer dereference in HS app causes segfault on telemetry request, directly enabling application DoS via exploitation (T1499.004).

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly validates Housekeeping Telemetry request inputs to reject malformed data before NULL dereference occurs.

prevent

Requires timely remediation of the identified NULL pointer flaw in the HS application.

prevent

Ensures graceful error handling for invalid telemetry data instead of segmentation fault and DoS.

detects

Security testing can detect NULL dereference defects before release.

prevents

Secure SDLC mandates defensive coding practices that can prevent NULL dereferences.

prevents

Application security requirements can specify input validation and pointer-safety rules.

prevents

Secure architecture principles encourage defensive design that avoids unsafe pointer use.

prevents

Secure coding standards directly require NULL-pointer checks and safe dereference patterns.
