wifi: ath6kl: fix OOB read from firmware IE lengths in connect event
Published Aug 10, 2026

HIGHCVSS 3.1
EPSS 0.42%
Description
The firmware-controlled beacon_ie_len, assoc_req_len, and assoc_resp_len fields in ath6kl_wmi_connect_event_rx() are not validated against the buffer length. Their sum (up to 765) can exceed the actual WMI event data, causing out-of-bounds reads during IE parsing and state corruption of wmi->is_wmm_enabled.
Add a check that the total IE length fits within the buffer.

Remediation
Red Hat statement
This issue affects Qualcomm ath6kl Wi-Fi. Firmware-controlled IE lengths in connect events are not validated against buffer size, causing OOB reads. Systems without ath6kl hardware are not affected.
Red Hat mitigation
To mitigate this issue, prevent the ath6kl module from loading. See https://access.redhat.com/solutions/41278 for instructions.
