Technical Description
The security fix for CVE-2025-0728 in eclipse-threadx NetX Duo refactors error handling in the HTTP server PUT process to use a shared cleanup label, but this unified cleanup path unconditionally calls fx_file_close() even when the file was never successfully opened. Multiple error branches jump to the shared cleanup label before any file open operation has occurred, causing fx_file_close() to operate on an uninitialized file handle, leading to undefined behavior, double-close issues, or memory corruption.
Remediation
Check the references section for vendor advisories and patches from eclipse. Update threadx_netx_duo to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
