Descriptions

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

bna: adjust 'name' buf size of bna_tcb and bna_ccb structures

To have enough space to write all possible sprintf() args. Currently
'name' size is 16, but the first '%s' specifier may already need at
least 16 characters, since 'bnad->netdev->name' is used there.

For '%d' specifiers, assume that they require:
* 1 char for 'tx_id + tx_info->tcb[i]->id' sum, BNAD_MAX_TXQ_PER_TX is 8
* 2 chars for 'rx_id + rx_info->rx_ctrl[i].ccb->id', BNAD_MAX_RXP_PER_RX
is 16

And replace sprintf with snprintf.

Detected using the static analysis tool - Svace.
