NVD Description

Note: Versions mentioned in the description apply only to the upstream u-boot package and not the u-boot package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

U-Boot before 2026.10-rc5 contains out-of-bounds memory access in dhcp6_parse_options() that fails to validate SERVERID and CLIENTID option lengths from DHCPv6 packets. Attackers on the local network can send crafted DHCPv6 ADVERTISE or REPLY packets during netboot to corrupt memory and crash the bootloader.
