[PATCH OLK-6.6] wifi: brcmfmac: fix crash while sending Action Frames in standalone AP Mode
by Fanhua Li 12 Dec '25

12 Dec '25

From: Gokul Sivakumar <gokulkumar.sivakumar(a)infineon.com> stable inclusion from stable-v6.6.117 commit 64e3175d1c8a3bea02032e7c9d1befd5f43786fa category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IDBAJ5 CVE: CVE-2025-40321 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 3776c685ebe5f43e9060af06872661de55e80b9a upstream. Currently, whenever there is a need to transmit an Action frame, the brcmfmac driver always uses the P2P vif to send the "actframe" IOVAR to firmware. The P2P interfaces were available when wpa_supplicant is managing the wlan interface. However, the P2P interfaces are not created/initialized when only hostapd is managing the wlan interface. And if hostapd receives an ANQP Query REQ Action frame even from an un-associated STA, the brcmfmac driver tries to use an uninitialized P2P vif pointer for sending the IOVAR to firmware. This NULL pointer dereferencing triggers a driver crash. [ 1417.074538] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000 [...] [ 1417.075188] Hardware name: Raspberry Pi 4 Model B Rev 1.5 (DT) [...] [ 1417.075653] Call trace: [ 1417.075662] brcmf_p2p_send_action_frame+0x23c/0xc58 [brcmfmac] [ 1417.075738] brcmf_cfg80211_mgmt_tx+0x304/0x5c0 [brcmfmac] [ 1417.075810] cfg80211_mlme_mgmt_tx+0x1b0/0x428 [cfg80211] [ 1417.076067] nl80211_tx_mgmt+0x238/0x388 [cfg80211] [ 1417.076281] genl_family_rcv_msg_doit+0xe0/0x158 [ 1417.076302] genl_rcv_msg+0x220/0x2a0 [ 1417.076317] netlink_rcv_skb+0x68/0x140 [ 1417.076330] genl_rcv+0x40/0x60 [ 1417.076343] netlink_unicast+0x330/0x3b8 [ 1417.076357] netlink_sendmsg+0x19c/0x3f8 [ 1417.076370] __sock_sendmsg+0x64/0xc0 [ 1417.076391] ____sys_sendmsg+0x268/0x2a0 [ 1417.076408] ___sys_sendmsg+0xb8/0x118 [ 1417.076427] __sys_sendmsg+0x90/0xf8 [ 1417.076445] __arm64_sys_sendmsg+0x2c/0x40 [ 1417.076465] invoke_syscall+0x50/0x120 [ 1417.076486] el0_svc_common.constprop.0+0x48/0xf0 [ 1417.076506] do_el0_svc+0x24/0x38 [ 1417.076525] el0_svc+0x30/0x100 [ 1417.076548] el0t_64_sync_handler+0x100/0x130 [ 1417.076569] el0t_64_sync+0x190/0x198 [ 1417.076589] Code: f9401e80 aa1603e2 f9403be1 5280e483 (f9400000) Fix this, by always using the vif corresponding to the wdev on which the Action frame Transmission request was initiated by the userspace. This way, even if P2P vif is not available, the IOVAR is sent to firmware on AP vif and the ANQP Query RESP Action frame is transmitted without crashing the driver. Move init_completion() for "send_af_done" from brcmf_p2p_create_p2pdev() to brcmf_p2p_attach(). Because the former function would not get executed when only hostapd is managing wlan interface, and it is not safe to do reinit_completion() later in brcmf_p2p_tx_action_frame(), without any prior init_completion(). And in the brcmf_p2p_tx_action_frame() function, the condition check for P2P Presence response frame is not needed, since the wpa_supplicant is properly sending the P2P Presense Response frame on the P2P-GO vif instead of the P2P-Device vif.

This attribute 32 indicates status of shutdown processing.The shutdown status values are defined 33 as: > 34 ====== ============================== 35 Value Definition 36 ====== ============================== 37 00b Normal operation 38 01b Shutdown processing occurring 39 10b Shutdown processing complete 40 11b Reserved 41 ====== ============================== > 42 The host csts_cfs attribute is a read only attribute. This attribute is set to 43 ’1’ when a fatal controller error occurred that could not be communicated in the 44 appropriate Completion Queue. This bit is cleared to ‘0’ when a fatal controller 45 error has not occurred. 46 47 The host csts_rdy attribute is a read only attribute. This attribute is set to 48 ‘1’ when the controller is ready to process submission queue entries. 49 50 The fw_version attribute is read-only and will return the driver version and the 51 controller firmware version. 52 -- 0-DAY CI Kernel Test Service https://github.com/intel/lkp-tests/wiki

This driver is used for Physical Function 15 (PF). 16 17 HiNIC3 devices support MSI-X interrupt vector for each Tx/Rx queue and 18 adaptive interrupt moderation. 19 20 HiNIC3 devices support also various offload features such as checksum offload, 21 TCP Transmit Segmentation Offload(TSO), Receive-Side Scaling(RSS) and 22 LRO(Large Receive Offload). 23 24 25 Supported PCI vendor ID/device IDs: 26 =================================== 27 28 19e5:1822 - HiNIC3 PF 29 30 31 Driver Architecture and Source Code: 32 ==================================== 33 34 hinic3_dev - Implement a Logical Network device that is independent from 35 specific HW details about HW data structure formats. 36 37 hinic3_hwdev - Implement the HW details of the device and include the components 38 for accessing the PCI NIC. 39 40 hinic3_hwdev contains the following components: 41 =============================================== 42 43 HW Interface: 44 ============= 45 46 The interface for accessing the pci device (DMA memory and PCI BARs). 47 (hinic3_hw_if.c, hinic3_hw_if.h) 48 49 Configuration Status Registers Area that describes the HW Registers on the 50 configuration and status BAR0. (hinic3_hw_csr.h) 51 52 MGMT components: 53 ================ 54 55 Asynchronous Event Queues(AEQs) - The event queues for receiving messages from 56 the MGMT modules on the cards. (hinic3_hw_eqs.c, hinic3_hw_eqs.h) 57 58 Application Programmable Interface commands(API CMD) - Interface for sending 59 MGMT commands to the card. (hinic3_hw_api_cmd.c, hinic3_hw_api_cmd.h) 60 61 Management (MGMT) - the PF to MGMT channel that uses API CMD for sending MGMT 62 commands to the card and receives notifications from the MGMT modules on the 63 card by AEQs. Also set the addresses of the IO CMDQs in HW. 64 (hinic3_hw_mgmt.c, hinic3_hw_mgmt.h) 65 66 IO components: 67 ============== 68 69 Completion Event Queues(CEQs) - The completion Event Queues that describe IO 70 tasks that are finished. (hinic3_hw_eqs.c, hinic3_hw_eqs.h) 71 72 Work Queues(WQ) - Contain the memory and operations for use by CMD queues and 73 the Queue Pairs. The WQ is a Memory Block in a Page. The Block contains 74 pointers to Memory Areas that are the Memory for the Work Queue Elements(WQEs). 75 (hinic3_hw_wq.c, hinic3_hw_wq.h) 76 77 Command Queues(CMDQ) - The queues for sending commands for IO management and is 78 used to set the QPs addresses in HW. The commands completion events are 79 accumulated on the CEQ that is configured to receive the CMDQ completion events. 80 (hinic3_hw_cmdq.c, hinic3_hw_cmdq.h) 81 82 Queue Pairs(QPs) - The HW Receive and Send queues for Receiving and Transmitting 83 Data. (hinic3_hw_qp.c, hinic3_hw_qp.h, hinic3_hw_qp_ctxt.h) 84 85 IO - de/constructs all the IO components. (hinic3_hw_io.c, hinic3_hw_io.h) 86 87 HW device: 88 ========== 89 90 HW device - de/constructs the HW Interface, the MGMT components on the 91 initialization of the driver and the IO components on the case of Interface 92 UP/DOWN Events.
