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. (NVD)

Monitor Linux's web page for any future patch releases.
