In the Linux kernel, the following vulnerability has been resolved: wifi: ath9k: fix OOB access from firmware tx status queue ID ath_tx_edma_tasklet() accesses sc->tx.txq[ts.qid] where ts.qid is a 4-bit hardware field (0-15), but the txq array only has ATH9K_NUM_TX_QUEUES (10) entries. A qid >= 10 causes an OOB array access. Add a bounds check on ts.qid before using it as an array index.
