{"schema":"threatline.record/2","record":{"id":"CVE-2026-98669","aliases":[],"summary":"iio: buffer: serialize buffer teardown with mode claims","details":"In the Linux kernel, the following vulnerability has been resolved:\n\niio: buffer: serialize buffer teardown with mode claims\n\nBuffer-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().\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 -> mlock ordering\nmatches iio_update_buffers().","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE
