CVE-2026-102715

mDNS string-cache lookup matches on slot size, so a peer name aliases a shorter one and the response encoder writes past the packet

publishedCWE-787CWE-697

In Eclipse ThreadX NetX Duo versions up to and including 6.5.2.202603, the mDNS add-on's string cache accepts a shorter name as a match for a longer stored one. A host on the local link can send two mDNS records that make a device performing continuous service discovery write up to three bytes past its transmit packet, corrupting a neighbouring packet or the pool's free list, and misattribute discovered records.
