CVE-2026-102713Unbounded DATA datagram in the NetX Duo TFTP server causes an out-of-bounds read and a permanent stall
High 8.3
In plain English
A high-severity out-of-bounds read in Eclipse ThreadX NetX Duo from Eclipse Foundation. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.3% (higher than 17% of all known vulnerabilities).
Official description
In Eclipse ThreadX NetX Duo versions up to and including 6.5.2.202603, built with packet chaining, the TFTP server does not bound the length of a received DATA datagram. An unauthenticated peer can upload an oversized datagram that writes memory beyond the received packet into the file and read it back by downloading the file, and the same datagram can suspend the server thread permanently.
