CVE-2025-39732

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

wifi: ath11k: fix sleeping-in-atomic in ath11k_mac_op_set_bitrate_mask()

ath11k_mac_disable_peer_fixed_rate() is passed as the iterator to

ieee80211_iterate_stations_atomic(). Note in this case the iterator is

required to be atomic, however ath11k_mac_disable_peer_fixed_rate() does

not follow it as it might sleep. Consequently below warning is seen:

BUG: sleeping function called from invalid context at wmi.c:304

Call Trace:

<TASK>

ath11k_wmi_cmd_send

ath11k_wmi_set_peer_param

ath11k_mac_disable_peer_fixed_rate

ieee80211_iterate_stations_atomic

ath11k_mac_op_set_bitrate_mask.cold

Change to ieee80211_iterate_stations_mtx() to fix this issue.
