CVE-2026-102721

Severity not reported
Data quality: awaiting analysis. NVD has not completed analysis, so CVSS and affected-product data may be missing or change.

A TFTP server that answers with a short ERROR packet makes the client read up to 64 bytes past the received datagram.

In Eclipse ThreadX NetX Duo versions 6.0 through 6.5.2.202603a, the TFTP client copies the message of a received ERROR packet without bounding the copy by the end of the datagram, and the TFTP server reads one byte past a minimal ERROR packet. A malicious TFTP server can make the client copy up to 64 bytes of adjacent packet-pool memory into the error string the application retrieves, or fault on targets with memory protection.
