      "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nvhost/vsock: always initialize seqpacket_allow\n\nThere are two issues around seqpacket_allow:\n1. seqpacket_allow is not initialized when socket is\n   created. Thus if features are never set, it will be\n   read uninitialized.\n2. if VIRTIO_VSOCK_F_SEQPACKET is set and then cleared,\n   then seqpacket_allow will not be cleared appropriately\n   (existing apps I know about don't usually do this but\n    it's legal and there's no way to be sure no one relies\n    on this).\n\nTo fix:\n\t- initialize seqpacket_allow after allocation\n\t- set it unconditionally in set_features"

      "value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: vhost/vsock: inicializar siempre seqpacket_allow Hay dos problemas relacionados con seqpacket_allow: 1. seqpacket_allow no se inicializa cuando se crea el socket. Por lo tanto, si las funciones nunca se configuran, se leer\u00e1 sin inicializar. 2. Si VIRTIO_VSOCK_F_SEQPACKET est\u00e1 configurado y luego borrado, entonces seqpacket_allow no se borrar\u00e1 apropiadamente (las aplicaciones existentes que conozco generalmente no hacen esto, pero es legal y no hay forma de estar seguro de que nadie conf\u00ede en esto). Para solucionarlo: - inicializar seqpacket_allow despu\u00e9s de la asignaci\u00f3n - configurarlo incondicionalmente en set_features"
