0 CVE-2026-55606 is a buffer over-read vulnerability in the odhcpd DHCPv6 server component used by OpenWrt. In versions 25.12 and earlier, the DHCPv6 self-loop detection code uses a network-byte-order DUID length value directly as the memcmp() size parameter, causing memcmp() to read beyond the allocated stack buffer on little-endian systems. This vulnerability can be triggered by a single unauthenticated DHCPv6 packet, resulting in a 2560-byte overread from a 128-byte buffer. No patches are publicly available at the time of publication.
