CVE-2018-14625

Estado: ModificadaAlta (7)—

Se ha detectado un error en el kernel de Linux en el que un atacante podría ser capaz de tener una lectura no controlada de la memoria del kernel desde dentro de una máquina virtual invitada. Una condición de carrera entre las funciones connect() y close() podría permitir que un atacante que emplee el protocolo AF_VSOCK reúna una filtración de información de 4 bytes o, posiblemente, intercepte o corrompa mensajes AF_VSOCK destinados a otros clientes
