CVE-2024-41090

  2. Vulnerabilities (CVE)
  3. CVE-2024-41090
In the Linux kernel, the following vulnerability has been resolved: tap: add missing verification for short frame The cited commit missed to check against the validity of the frame length in the tap_get_user_xdp() path, which could cause a corrupted skb to be sent downstack. Even before the skb is transmitted, the tap_get_user_xdp()-->skb_set_network_header() may assume the size is more than ETH_HLEN. Once transmitted, this could either cause out-of-bound access beyond the actual length, or confuse the underlayer with incorrect or inconsistent header length in the skb metadata. In the alternative path, tap_get_user() already prohibits short frame which has the length less than Ethernet header size from being transmitted. This is to drop any frame shorter than the Ethernet header size just like how tap_get_user() does. CVE: CVE-2024-41090

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: tap: agregar verificación faltante para marco corto La confirmación citada no pudo verificar la validez de la longitud del marco en la ruta tap_get_user_xdp(), lo que podría causar que un skb corrupto se envíe hacia abajo. Incluso antes de que se transmita el skb, tap_get_user_xdp()-->skb_set_network_header() puede asumir que el tamaño es mayor que ETH_HLEN. Una vez transmitido, esto podría provocar un acceso fuera de los límites más allá de la longitud real o confundir la capa subyacente con una longitud de encabezado incorrecta o inconsistente en los metadatos de skb. En la ruta alternativa, tap_get_user() ya prohíbe la transmisión de tramas cortas que tengan una longitud menor que el tamaño del encabezado Ethernet. Esto es para eliminar cualquier trama más corta que el tamaño del encabezado de Ethernet tal como lo hace tap_get_user(). CVE: CVE-2024-41090
