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

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.

CVSS 3.1 HIGH 416baaa9-dc9f-4396-8d5f-8c081fb06d67
Solution
Validate IE lengths against buffer size to prevent out-of-bounds reads.
  • Apply the Linux kernel patch for ath6kl.
  • Validate firmware IE lengths before processing.
  • Ensure IE lengths do not exceed buffer capacity.
