Descriptions

EDK2's Network Package is susceptible to an out-of-bounds read
vulnerability when processing  Neighbor Discovery Redirect message. This
vulnerability can be exploited by an attacker to gain unauthorized
access and potentially lead to a loss of Confidentiality.

El paquete de red de EDK2 es susceptible a una vulnerabilidad de lectura fuera de los límites al procesar el mensaje de redirección de descubrimiento de vecinos. Un atacante puede aprovechar esta vulnerabilidad para obtener acceso no autorizado y potencialmente provocar una pérdida de confidencialidad.

A security loophole involving an out-of-bounds read was identified in EDK2, the open-source reference implementation of the UEFI specification. This vulnerability enables an unauthorized attacker within the vicinity of the network to transmit a specifically crafted Neighbor Discovery Redirect message. Consequently, this may lead to the unauthorized reading of memory beyond the message boundaries, potentially resulting in the exposure of sensitive information.
