Jul 19, 2026In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: bounds-check link_id in ieee80211_ml_epcs IEEE80211_MLE_STA_EPCS_CONTROL_LCVE-2026-64030 · Computers, phones & browsers · Linux · reported by 416baaa9-dc9f-4396-8d5f-8c081fb06d67High 8.8
In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: bounds-check link_id in ieee80211_ml_epcs IEEE80211_MLE_STA_EPCS_CONTROL_LINK_ID is 0x000f, so link_id extracted from a PRIO_ACCESS ML element PER_STA_PROFILE subelement can be 0..15. sdata->link[] has IEEE80211_MLD_MAX_NUM_LINKS (15) entries (indices 0..14), making index 15 out-of-bounds. A connected WiFi 7 AP can trigger this by sending an EPCS Enable Response action frame with a PER_STA_PROFILE subelement where link_id = 15. The unsolicited-notification path (dialog_token = 0) is reachable any time EPCS is already enabled, without any prior client request. sdata->link[15] reads into the first word of sdata->activate_links_work (a wiphy_work whose embedded list_head is non-NULL after INIT_LIST_HEAD), so the NULL check on the result does not catch the invalid access. The garbage pointer is then passed to ieee80211_sta_wmm_params(), which dereferences link->sdata and crashes the kernel. The same class of bug was fixed for ieee80211_ml_reconfiguration() by commit 162d331d833d ("wifi: mac80211: bounds-check link_id in ieee80211_ml_reconfiguration").

Jul 19, 2026In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: limit injected antenna index in ieee80211_parse_tx_radiotap When parsing tCVE-2026-63869 · Computers, phones & browsers · Linux · reported by 416baaa9-dc9f-4396-8d5f-8c081fb06d67High 7.6
In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: limit injected antenna index in ieee80211_parse_tx_radiotap When parsing the radiotap header of an injected frame, ieee80211_parse_tx_radiotap() uses the IEEE80211_RADIOTAP_ANTENNA value directly as a shift count: info->control.antennas |= BIT(*iterator.this_arg); *iterator.this_arg is an 8-bit value taken straight from the frame supplied by userspace, so BIT() can be asked to shift by up to 255. That is undefined behaviour on the unsigned long and is reported by UBSAN: UBSAN: shift-out-of-bounds in net/mac80211/tx.c:2174:30 shift exponent 235 is too large for 64-bit type 'unsigned long' Call Trace: ieee80211_parse_tx_radiotap+0xadb/0x1950 net/mac80211/tx.c:2174 ieee80211_monitor_start_xmit+0xb1f/0x1250 net/mac80211/tx.c:2451 ... packet_sendmsg+0x3eb6/0x50f0 net/packet/af_packet.c:3109 info->control.antennas is a 2-bit bitmap (u8 antennas:2), so only antenna indices 0 and 1 can ever be represented. Ignore any larger value instead of shifting out of bounds.

Jul 19, 2026In the Linux kernel, the following vulnerability has been resolved: wifi: rtw88: usb: fix memory leaks on USB write failures When rtw_usb_write_port() fails tCVE-2026-63821 · Computers, phones & browsers · Linux · reported by 416baaa9-dc9f-4396-8d5f-8c081fb06d67
In the Linux kernel, the following vulnerability has been resolved: wifi: rtw88: usb: fix memory leaks on USB write failures When rtw_usb_write_port() fails to submit a USB Request Block (URB) (e.g., due to device disconnect or ENOMEM), the completion callback is never executed. Currently, the driver ignores the return value of rtw_usb_write_port() in rtw_usb_write_data() and rtw_usb_tx_agg_skb(). Because these functions rely on the completion callback to free the socket buffers (skbs) and the transaction control block (txcb), a submission failure results in: 1. A memory leak of the allocated skb in rtw_usb_write_data(). 2. A memory leak of the txcb structure and all aggregated skbs in rtw_usb_tx_agg_skb(). Fix this by checking the return value of rtw_usb_write_port(). If it fails, explicitly free the skb in rtw_usb_write_data(), and properly purge the tx_ack_queue and free the txcb in rtw_usb_tx_agg_skb(). The issue was discovered in practice during device disconnect/reconnect scenarios and memory pressure conditions. Tested by verifying normal TX operation continues after the fix without regressions.

The nRF70 Wi-Fi driver's power-save event handler nrf_wifi_event_proc_get_power_save_info() in drivers/wifi/nrf_wifi/src/wifi_mgmt.c copied TWT (Target Wake Time) flow entries from an nrf_wifi_umac_event_power_save_info event into the fixed-size twt_flows[WIFI_MAX_TWT_FLOWS] (8-element) array of a caller-supplied struct wifi_ps_config, looping over event-provided num_twt_flows without validating it against WIFI_MAX_TWT_FLOWS or checking event_len. When num_twt_flows exceeds 8, the handler writes past the destination array (which is typically on the caller's stack, e.g. the wifi ps shell command) -- an out-of-bounds write of ~40-byte TWT entries -- and reads twt_flow_info[i] past the event buffer. The event is delivered by the nRF70 co-processor firmware in response to a host-initiated power-save GET, so reaching the overflow requires the firmware to emit a malformed or out-of-range event; the trust boundary is host-to-trusted-coprocessor rather than a direct remote-AP write, with over-the-air influence on the flow count being indirect and bounded by the 3-bit TWT flow-id space. Affected: builds with CONFIG_NRF70_STA_MODE on releases through v4.4.0. The fix rejects events with num_t

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7921: Place upper limit on station AID Any station configured with an AID over 20 causes a firmware crash. This situation occurred in our testing using an AP interface on 7922 hardware, with a modified hostapd, sourced from Mediatek's OpenWRT feeds. In stock hostapd, station AIDs begin counting at 1, and this configuration is prevented with an upper limit on associated stations. However, the modified hostapd began allocation at 65, which caused the firmware to crash. This fix does not allow these AIDs to work, but will prevent the firmware crash. This crash was only seen on IFTYPE_AP interfaces, and the fix does not appear to have an effect on IFTYPE_STATION behavior.

In the Linux kernel, the following vulnerability has been resolved: wifi: rtlwifi: pci: fix possible use-after-free caused by unfinished irq_prepare_bcn_tasklet The irq_prepare_bcn_tasklet is initialized in rtl_pci_init() and scheduled when RTL_IMR_BCNINT interrupt is triggered by hardware. But it is never killed in rtl_pci_deinit(). When the rtlwifi card probe fails or is being detached, the ieee80211_hw is deallocated. However, irq_prepare_bcn_tasklet may still be running or pending, leading to use-after-free when the freed ieee80211_hw is accessed in _rtl_pci_prepare_bcn_tasklet(). Similar to irq_tasklet, add tasklet_kill() in rtl_pci_deinit() to ensure that irq_prepare_bcn_tasklet is properly terminated before the ieee80211_hw is released. The issue was identified through static analysis.

In the Linux kernel, the following vulnerability has been resolved: wifi: libertas: don't kill URBs in interrupt context Serialization for the TX path was enforced by calling usb_kill_urb()/usb_kill_anchored_urbs(), to prevent transmission before a previous URB was completed. usb_tx_block() can be called from interrupt context (e.g. in the HCD giveback path), so we can't always use it to kill in-flight URBs. Prevent sleeping during interrupt context by checking the tx_submitted anchor for existing URBs. We now return -EBUSY, to indicate there's a pending request.

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7925: fix potential deadlock in mt7925_roc_abort_sync roc_abort_sync() can deadlock with roc_work(). roc_work() holds dev->mt76.mutex, while cancel_work_sync() waits for roc_work() to finish. If the caller already owns the same mutex, both sides block and no progress is possible. This deadlock can occur during station removal when mt76_sta_state() -> mt76_sta_remove() -> mt7925_mac_sta_remove_link() -> mt7925_mac_link_sta_remove() -> mt7925_roc_abort_sync() invokes cancel_work_sync() while roc_work() is still running and holding dev->mt76.mutex. This avoids the mutex deadlock and preserves exactly-once work ownership.

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: Fix memory leak after mt76_connac_mcu_alloc_sta_req() mt76_connac_mcu_alloc_sta_req() allocates an skb which is expected to be freed eventually by mt76_mcu_skb_send_msg(). However, currently if an intermediate function fails before sending, the allocated skb is leaked. Specifically, mt76_connac_mcu_sta_wed_update() and mt76_connac_mcu_sta_key_tlv() may fail, leading to an immediate memory leak in the error path. Fix this by explicitly freeing the skb in these error paths. Commit 7c0f63fe37a5 ("wifi: mt76: mt7996: fix memory leak on mt7996_mcu_sta_key_tlv error") made a similar change. Compile tested only.

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7921: fix potential deadlock in mt7921_roc_abort_sync roc_abort_sync() can deadlock with roc_work(). roc_work() holds dev->mt76.mutex, while cancel_work_sync() waits for roc_work() to finish. If the caller already owns the same mutex, both sides block and no progress is possible. This deadlock can occur during station removal when mt76_sta_state() -> mt76_sta_remove() -> mt7921_mac_sta_remove() -> mt7921_roc_abort_sync() invokes cancel_work_sync() while roc_work() is still running and holding dev->mt76.mutex. This avoids the mutex deadlock and preserves exactly-once work ownership.

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: fix deadlock in remain-on-channel mt76_remain_on_channel() and mt76_roc_complete() call mt76_set_channel() while already holding dev->mutex. Since mt76_set_channel() also acquires dev->mutex, this results in a deadlock. Use __mt76_set_channel() instead of mt76_set_channel(). Add cancel_delayed_work_sync() for mac_work before acquiring the mutex in mt76_remain_on_channel() to prevent a secondary deadlock with the mac_work workqueue.

During WiFi association, Naxclow device firmware prints the host network’s SSID, PSK, and negotiated WPA keys in cleartext to an exposed UART console on production hardware. The UART pads are labeled, run with default serial settings, and drop to an interactive RT-Thread shell that permits arbitrary memory reads, enabling full firmware extraction. An attacker with brief physical access, common for outdoor-mounted devices, can therefore recover WiFi credentials and bootstrap firmware-side attacks.
