Summary

CVE-2025-55078 is a medium-severity Improper Handling of Parameters (CWE-233) vulnerability in Eclipse Threadx. Its CVSS base score is 5.7 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 6th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

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

Vulnerability Data

In Eclipse ThreadX before version 6.4.3, an attacker can cause a denial of service (crash) by providing a pointer to a reserved or unmapped memory region. Vulnerable system calls had a check of pointers, but that check wasn't verifying whether…

finds

Security testing can detect missing-parameter issues but does not prevent them at design time.

prevents

Secure development lifecycle includes input validation and parameter handling requirements that reduce improper parameter handling.

prevents

Application security requirements explicitly call for validation of inputs and parameters, mitigating missing or undefined arguments.

prevents

Secure coding standards directly address proper handling of function parameters and input validation.
