NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-uek-debug-modules-wireless package and not the kernel-uek-debug-modules-wireless package as distributed by Oracle. See How to fix? for Oracle:10 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: btusb: reorder cleanup in btusb_disconnect to avoid UAF

There is a KASAN: slab-use-after-free read in btusb_disconnect(). Calling "usb_driver_release_interface(&btusb_driver, data->intf)" will free the btusb data associated with the interface. The same data is then used later in the function, hence the UAF.

Fix by moving the accesses to btusb data to before the data is free'd.
