Description
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.
