  2. Vulnerabilities (CVE)
  3. 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> dump_stack_lvl __might_resched.cold 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. Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.30

Summary
  • (es) En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: wifi: ath11k: corregir sleeping-in-atomic en ath11k_mac_op_set_bitrate_mask() ath11k_mac_disable_peer_fixed_rate() se pasa como el iterador a ieee80211_iterate_stations_atomic(). Tenga en cuenta que en este caso se requiere que el iterador sea atómico, sin embargo, ath11k_mac_disable_peer_fixed_rate() no lo sigue ya que podría dormir. Consecuentemente, se observa la siguiente advertencia: ERROR: función en suspensión llamada desde un contexto inválido en wmi.c:304 Traza de Llamada: <TAREA> dump_stack_lvl __might_resched.cold 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 Cambiar a ieee80211_iterate_stations_mtx() para solucionar este problema. Probado en: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.30
