| Subject: CVE-2022-48928: iio: adc: men_z188_adc: Fix a resource leak in an error handling path |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| iio: adc: men_z188_adc: Fix a resource leak in an error handling path |
| |
| If iio_device_register() fails, a previous ioremap() is left unbalanced. |
| |
| Update the error handling path and add the missing iounmap() call, as |
| already done in the remove function. |
| |
| The Linux kernel CVE team has assigned CVE-2022-48928 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: |
