  "summary": "bna: adjust 'name' buf size of bna_tcb and bna_ccb structures",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nbna: adjust 'name' buf size of bna_tcb and bna_ccb structures\n\nTo have enough space to write all possible sprintf() args. Currently\n'name' size is 16, but the first '%s' specifier may already need at\nleast 16 characters, since 'bnad->netdev->name' is used there.\n\nFor '%d' specifiers, assume that they require:\n * 1 char for 'tx_id + tx_info->tcb[i]->id' sum, BNAD_MAX_TXQ_PER_TX is 8\n * 2 chars for 'rx_id + rx_info->rx_ctrl[i].ccb->id', BNAD_MAX_RXP_PER_RX\n   is 16\n\nAnd replace sprintf with snprintf.\n\nDetected using the static analysis tool - Svace.",
