Description
CVE-2026-102720 is an out-of-bounds read vulnerability in Eclipse ThreadX NetX Duo versions 6.0 through 6.5.2.202603a. The DHCP client improperly advances its option walk offset, causing it to read up to about one kilobyte beyond the received DHCP message. This can lead to copying out-of-bounds bytes into the application's buffer when retrieving user options.
