CVE-2021-46949

CVE-2021-46949 concerns the Linux kernel sfc (Solarflare) network driver path: farch TX queue lookup during TX flush done handling. The root cause is starting TXQ processing from a TXQ instance number (qid) rather than a TXQ type, which could cause efx_get_tx_queue() to return NULL and trigger pa...
