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...

CVE-2021-46948

CVE-2021-46948 relates to the Linux kernel: the sfc: farch patch fixes TX queue lookup in TX event handling. The issue occurred because TXQ label was used as the basis for queue lookup, which could cause efx_channel_get_tx_queue() to return NULL and trigger panics. The vulnerability has been reso...

CVE-2021-46947 sfc: adjust efx->xdp_tx_queue_count with the real number of initialized queues

In the Linux kernel, the following vulnerability has been resolved: sfc: adjust efx-xdptxqueuecount with the real number of initialized queues efx-xdptxqueuecount is initially initialized to numpossiblecpus and is later used to allocate and traverse efx-xdptxqueues lookup array. However, we may e...

CVE-2021-46947

CVE-2021-46947 is a Linux kernel issue in the sfc (Solarflare) driver where efx->xdp_tx_queue_count can reflect too many uninitialized slots after probing, risking a NULL pointer dereference (e.g., when running ethtool -S). The root cause is that xdp_tx_queue_count starts at num_possible_cpus(...

kernel: sfc: fix considering that all channels have TX queues

In the Linux kernel, the following vulnerability has been resolved: sfc: fix considering that all channels have TX queues Normally, all channels have RX and TX queues, but this is not true if modparam efxseparatetxchannels=1 is used. In that cases, some channels only have RX queues and others onl...
