| Subject: CVE-2024-57904: iio: adc: at91: call input_free_device() on allocated iio_dev |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| iio: adc: at91: call input_free_device() on allocated iio_dev |
| |
| Current implementation of at91_ts_register() calls input_free_deivce() |
| on st->ts_input, however, the err label can be reached before the |
| allocated iio_dev is stored to st->ts_input. Thus call |
| input_free_device() on input instead of st->ts_input. |
| |
| The Linux kernel CVE team has assigned CVE-2024-57904 to this issue. |

| Mitigation |
| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
| stable kernel version for this, and many other bugfixes. Individual |
| changes are never tested alone, but rather are part of a larger kernel |
| release. Cherry-picking individual commits is not recommended or |
| supported by the Linux kernel community at all. If however, updating to |
| the latest release is impossible, the individual changes to resolve this |
| issue can be found at these commits: |
