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.

No CVSS v4.0

No CVSS v3.1

No CVSS v3.0

No CVSS v2

This CVE is not in the KEV list.

The EPSS score is 0.00176.
