CVE-2025-39732

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> wifi: ath11k: fix sleeping-in-atomic in ath11k_mac_op_set_bitrate_mask()<br /> <br /> ath11k_mac_disable_peer_fixed_rate() is passed as the iterator to<br /> ieee80211_iterate_stations_atomic(). Note in this case the iterator is<br /> required to be atomic, however ath11k_mac_disable_peer_fixed_rate() does<br /> not follow it as it might sleep. Consequently below warning is seen:<br /> <br /> BUG: sleeping function called from invalid context at wmi.c:304<br /> Call Trace:<br /> <br /> dump_stack_lvl<br /> __might_resched.cold<br /> ath11k_wmi_cmd_send<br /> ath11k_wmi_set_peer_param<br /> ath11k_mac_disable_peer_fixed_rate<br /> ieee80211_iterate_stations_atomic<br /> ath11k_mac_op_set_bitrate_mask.cold<br /> <br /> Change to ieee80211_iterate_stations_mtx() to fix this issue.<br /> <br /> Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.30
