{"id":"CVE-2025-71199","summary":"iio: adc: at91-sama5d2_adc: Fix potential use-after-free in sama5d2_adc driver","details":"In the Linux kernel, the following vulnerability has been resolved:\n\niio: adc: at91-sama5d2_adc: Fix potential use-after-free in sama5d2_adc driver\n\nat91_adc_interrupt can call at91_adc_touch_data_handler function\nto start the work by schedule_work(&st-\u003etouch_st.workq).\n\nIf we remove the module which will call at91_adc_remove to\nmake cleanup, it will free indio_dev through iio_device_unregister but\nquite a bit later. While the work mentioned above will be used.
