--- title: "CVE-2026-80947\n | Ubuntu" description: Ubuntu is an open source software operating system that runs from the desktop, to the cloud, to all your internet connected things. url: https://ubuntu.com/security/CVE-2026-80947?format=md keywords: index, follow --- # CVE-2026-80947 Publication date 14 September 2026 Last updated 14 September 2026 --- Ubuntu priority **Medium** [Why this priority?](https://ubuntu.com/security/cves/about#priority ) Toggle side navigation ## Description In the Linux kernel, the following vulnerability has been resolved: wifi: rtl8xxxu: fix use-after-free from rx\_urb\_wq on stop rtl8xxxu arms rx\_urb\_wq from the RX completion path: rtl8xxxu\_rx\_complete() hands the URB to rtl8xxxu\_queue\_rx\_urb(), which queues it on rx\_urb\_pending\_list and, once the list grows past RTL8XXXU\_RX\_URB\_PENDING\_WATER, schedules rx\_urb\_wq. The worker rtl8xxxu\_rx\_urb\_work() drains rx\_urb\_pending\_list, recovers priv through container\_of, and resubmits each URB through rtl8xxxu\_submit\_rx\_urb(), which anchors it on rx\_anchor and dereferences priv->udev. rtl8xxxu\_stop() cancels the sibling work items (c2hcmd\_work, ra\_watchdog, update\_beacon\_work) but never cancels rx\_urb\_wq, so a worker armed during the last burst of RX traffic can run rtl8xxxu\_rx\_urb\_work() after rtl8xxxu\_disconnect() has called ieee80211\_free\_hw(), which frees priv, producing a use-after-free. The window opens under active RX traffic (pending count above the watermark) followed by a disconnect. There are two teardown races to close: \* rtl8xxxu\_queue\_rx\_urb() decided whether to enqueue under rx\_urb\_lock but called schedule\_work() after dropping the lock. A completion that observed shutdown == false and released the lock could then call schedule\_work() after rtl8xxxu\_stop() had set shutdown and cancel\_work\_sync() had already returned, arming the worker to run after the teardown. Move schedule\_work() under the same !shutdown branch so the arming decision is atomic with the shutdown check. \* rtl8xxxu\_rx\_urb\_work() anchors every URB it drained back onto rx\_anchor through rtl8xxxu\_submit\_rx\_urb(). A worker still running when usb\_kill\_anchored\_urbs(&priv->rx\_anchor) returned would submit a URB that escaped the kill. In rtl8xxxu\_stop(), call cancel\_work\_sync(&priv->rx\_urb\_wq) before the kill so the worker is drained first. After priv->shutdown is set under rx\_urb\_lock, completions can no longer queue rx\_urb\_wq. cancel\_work\_sync() then drains the last queued or running worker, and the following usb\_kill\_anchored\_urbs() kills the URBs it may have submitted. rtl8xxxu\_disconnect() is covered because ieee80211\_unregister\_hw() guarantees .stop() runs for a live interface before ieee80211\_free\_hw() frees priv. The probe error path needs no cancel: rx\_urb\_wq is INIT\_WORK()'d there but cannot have been scheduled, since no URB is submitted before ieee80211\_register\_hw() succeeds. This bug was found by static analysis. ## Status Show unmaintained releases | Package | Ubuntu Release | Status | | --- | --- | --- | | linux | 26.04 LTS resolute | Needs evaluation | | 24.04 LTS
