Unbounded PPP IPCP Option Parsing Causes a Worker Stall and Out-of-bounds Read

Published Sep 29, 2026 CVSS 4.0 · 7.1 High EPSS < 1% KEV · Not listed
Description
In Eclipse ThreadX NetX Duo versions 6.0 through 6.5.2.202603a, the PPP IPCP code parses a peer's Configure-Nak without validating each option's length. A malicious PPP peer can stall the PPP thread indefinitely with a zero-length option, taking the link down, and can read back up to four bytes of packet-buffer memory per exchange with a short address option.
