CVE-2025-40283

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> Bluetooth: btusb: reorder cleanup in btusb_disconnect to avoid UAF<br /> <br /> There is a KASAN: slab-use-after-free read in btusb_disconnect().<br /> Calling "usb_driver_release_interface(&amp;btusb_driver, data-&gt;intf)" will<br /> free the btusb data associated with the interface. The same data is<br /> then used later in the function, hence the UAF.<br /> <br /> Fix by moving the accesses to btusb data to before the data is free&amp;#39;d.
