Summary		(es) Los invitados pueden provocar un punto muerto en Linux netback driver T. Este registro de información CNA se relaciona con múltiples CVE; el texto explica qué aspectos/vulnerabilidades corresponden a cada CVE.] El parche para XSA-392 introdujo otro problema que podría resultar en un punto muerto al intentar liberar el SKB de un paquete caído debido al manejo de XSA-392 (CVE-2022- 42328). Además, al descartar paquetes por otros motivos, podría producirse el mismo punto muerto en caso de que netpoll esté activo para la interfaz a la que está conectado el controlador xen-netback (CVE-2022-42329).
