CVE-2026-68352 PUBLISHED

wifi: ath6kl: fix OOB read from firmware IE lengths in connect event

Assigner: Linux
Reserved: 30.07.2026 Published: 10.08.2026 Updated: 10.08.2026

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

wifi: ath6kl: fix OOB read from firmware IE lengths in connect event

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.
