Title
iio: adc: at91-sama5d2_adc: Fix potential use-after-free in sama5d2_adc driver
Summary
In the Linux kernel, the following vulnerability has been resolved:
iio: adc: at91-sama5d2_adc: Fix potential use-after-free in sama5d2_adc driver
at91_adc_interrupt can call at91_adc_touch_data_handler function
to start the work by schedule_work(&st->touch_st.workq).
If we remove the module which will call at91_adc_remove to
make cleanup, it will free indio_dev through iio_device_unregister but
quite a bit later. While the work mentioned above will be used. The
sequence of operations that may lead to a UAF bug is as follows:
CPU0 CPU1
| at91_adc_workq_handler
at91_adc_remove |
iio_device_unregister(indio_dev) |
//free indio_dev a bit later |
| iio_push_to_buffers(indio_dev)
| //use indio_dev
Fix it by ensuring that the work is canceled before proceeding with
the cleanup in at91_adc_remove.
Severity
No CVSS data available.
