Technical description

In the Linux kernel, the following vulnerability has been resolved:

wifi: ath9k: Fix potential array-index-out-of-bounds read in ath9k_htc_txstatus()

Fix an array-index-out-of-bounds read in ath9k_htc_txstatus(). The bug

occurs when txs->cnt, data from a URB provided by a USB device, is

bigger than the size of the array txs->txstatus, which is

HTC_MAX_TX_STATUS. WARN_ON() already checks it, but there is no bug

handling code after the check. Make the function return if that is the

case.

Found by a modified version of syzkaller.

UBSAN: array-index-out-of-bounds in htc_drv_txrx.c

index 13 is out of range for type '__wmi_event_txstatus [12]'

Call Trace:

ath9k_htc_txstatus

ath9k_wmi_event_tasklet

tasklet_action_common

__do_softirq

irq_exit_rxu

sysvec_apic_timer_interrupt

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
