Descriptions

In the Linux kernel, the following vulnerability has been resolved:

sfc: farch: fix TX queue lookup in TX event handling

We're starting from a TXQ label, not a TXQ type, so
efx_channel_get_tx_queue() is inappropriate (and could return NULL,
leading to panics).

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: sfc: farch: corrige la búsqueda de cola TX en el manejo de eventos TX Estamos comenzando desde una etiqueta TXQ, no un tipo TXQ, por lo que efx_channel_get_tx_queue() es inapropiado (y podría devolver NULL, provocando pánico).
