  "description": "In the Linux kernel, the following vulnerability has been resolved:  wifi: ath11k: use work queue to process beacon tx event  Commit 3a415daa3e8b (\u0022wifi: ath11k: add P2P IE in beacon template\u0022) from Feb 28, 2024 (linux-next), leads to the following Smatch static checker warning:  drivers/net/wireless/ath/ath11k/wmi.c:1742 ath11k_wmi_p2p_go_bcn_ie() warn: sleeping in atomic context  The reason is that ath11k_bcn_tx_status_event() will directly call might sleep function ath11k_wmi_cmd_send() during RCU read-side critical sections. The call trace is like:  ath11k_bcn_tx_status_event() -\u003E rcu_read_lock() -\u003E ath11k_mac_bcn_tx_event() \t-\u003E ath11k_mac_setup_bcn_tmpl() \t\u2026\u2026 \t\t-\u003E ath11k_wmi_bcn_tmpl() \t\t\t-\u003E ath11k_wmi_cmd_send() -\u003E rcu_read_unlock()  Commit 886433a98425 (\u0022ath11k: add support for BSS color change\u0022) added the ath11k_mac_bcn_tx_event(), commit 01e782c89108 (\u0022ath11k: fix warning of RCU usage for ath11k_mac_get_arvif_by_vdev_id()\u0022) added the RCU lock to avoid warning but also introduced this BUG.  Use work queue to avoid directly calling ath11k_mac_bcn_tx_event() during RCU critical sections. No need to worry about the deletion of vif because cancel_work_sync() will drop the work if it doesn\u0027t start or block vif deletion until the running work is done.
