Vulnerability Title
wifi: ath11k: use work queue to process beacon tx event
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: wifi: ath11k: use work queue to process beacon tx event Commit 3a415daa3e8b ("wifi: ath11k: add P2P IE in beacon template") 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() -> rcu_read_lock() -> ath11k_mac_bcn_tx_event() -> ath11k_mac_setup_bcn_tmpl() …… -> ath11k_wmi_bcn_tmpl() -> ath11k_wmi_cmd_send() -> rcu_read_unlock() Commit 886433a98425 ("ath11k: add support for BSS color change") added the ath11k_mac_bcn_tx_event(), commit 01e782c89108 ("ath11k: fix warning of RCU usage for ath11k_mac_get_arvif_by_vdev_id()") 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't start or block vif deletion until the running work is done.
