Descriptions
In the Linux kernel, the following vulnerability has been resolved:
sfc: farch: fix TX queue lookup in TX flush done handling
We're starting from a TXQ instance number ('qid'), not a TXQ type, so
efx_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 la cola TX en el manejo finalizado del vaciado TX. Estamos comenzando desde un número de instancia TXQ ('qid'), no un tipo TXQ, por lo que efx_get_tx_queue() es inapropiado (y podría devolver NULL, lo que provocaría pánico).
