Title
iio: buffer: serialize buffer teardown with mode claims
Summary
In the Linux kernel, the following vulnerability has been resolved: iio: buffer: serialize buffer teardown with mode claims Buffer-mode claims hold mlock to guarantee that the device remains in buffer mode until the claim is released. Normal buffer updates take info_exist_lock followed by mlock in iio_update_buffers(). However, iio_device_unregister() disables and deactivates all buffers without taking mlock. This can invalidate buffer state, including active_scan_mask, while a buffer-mode claim is held. Take mlock in iio_disable_all_buffers() so that unregister honors the mode-claim lifetime guarantee. The info_exist_lock -> mlock ordering matches iio_update_buffers().

Normal buffer updates take\ninfo_exist_lock followed by mlock in iio_update_buffers().\n\nHowever, iio_device_unregister() disables and deactivates all buffers\nwithout taking mlock. This can invalidate buffer state, including\nactive_scan_mask, while a buffer-mode claim is held.\n\nTake mlock in iio_disable_all_buffers() so that unregister honors the\nmode-claim lifetime guarantee. The info_exist_lock -\u003e mlock ordering\nmatches iio_update_buffers()."
