CVE-2024-35958

  2. Vulnerabilities (CVE)
  3. CVE-2024-35958
In the Linux kernel, the following vulnerability has been resolved: net: ena: Fix incorrect descriptor free behavior ENA has two types of TX queues: - queues which only process TX packets arriving from the network stack - queues which only process TX packets forwarded to it by XDP_REDIRECT or XDP_TX instructions The ena_free_tx_bufs() cycles through all descriptors in a TX queue and unmaps + frees every descriptor that hasn't been acknowledged yet by the device (uncompleted TX transactions). The function assumes that the processed TX queue is necessarily from the first category listed above and ends up using napi_consume_skb() for descriptors belonging to an XDP specific queue. This patch solves a bug in which, in case of a VF reset, the descriptors aren't freed correctly, leading to crashes.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: ena: soluciona el comportamiento incorrecto sin descriptor. ENA tiene dos tipos de colas TX: - colas que solo procesan paquetes TX que llegan desde la pila de red - colas que solo procesan paquetes TX reenviados a mediante instrucciones XDP_REDIRECT o XDP_TX. Ena_free_tx_bufs() recorre todos los descriptores en una cola de TX y desasigna + libera todos los descriptores que aún no han sido reconocidos por el dispositivo (transacciones de TX incompletas). La función supone que la cola TX procesada es necesariamente de la primera categoría enumerada anteriormente y termina usando napi_consume_skb() para los descriptores que pertenecen a una cola XDP específica. Este parche resuelve un error por el cual, en caso de restablecer VF, los descriptores no se liberan correctamente, lo que provoca fallos.
