EDK2's Network Package es susceptible a una vulnerabilidad de lectura fuera de los límites cuando procesa la opción IA_NA o IA_TA en un mensaje de publicidad DHCPv6. Un atacante puede aprovechar esta vulnerabilidad para obtener acceso no autorizado y potencialmente provocar una pérdida de confidencialidad.

A vulnerability has been identified in the NetworkPkg IP stack of EDK2, the open-source reference implementation of the UEFI specification. This flaw enables an unauthenticated attacker within the same network vicinity to transmit a specifically crafted DHCPv6 message. Exploiting this vulnerability may result in unauthorized access to memory beyond its boundaries, potentially leading to the exposure of sensitive information.
