In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
iio: buffer: serialize buffer teardown with mode claims<\/p>\n
Buffer-mode claims hold mlock to guarantee that the device remains in
\nbuffer mode until the claim is released. Normal buffer updates take
\ninfo_exist_lock followed by mlock in iio_update_buffers().<\/p>\n
However, 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.<\/p>\n
Take mlock in iio_disable_all_buffers() so that unregister honors the
\nmode-claim lifetime guarantee. The info_exist_lock -> mlock ordering
\nmatches iio_update_buffers().<\/p>\n","protected":false},"excerpt":{"rendered":"
