{"id":"DEBIAN-CVE-2022-49378","details":"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 efx_separate_tx_channels=1 is used. In that cases, some channels only have RX queues and others only TX queues (or more preciselly, they have them allocated, but not initialized).  Fix efx_channel_has_tx_queues to return the correct value for this case too.
