| Subject: CVE-2024-57908: iio: imu: kmx61: fix information leak in triggered buffer |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| iio: imu: kmx61: fix information leak in triggered buffer |
| |
| The 'buffer' local array is used to push data to user space from a |
| triggered buffer, but it does not set values for inactive channels, as |
| it only uses iio_for_each_active_channel() to assign new values. |
| |
| Initialize the array to zero before using it to avoid pushing |
| uninitialized information to userspace. |
| |
| The Linux kernel CVE team has assigned CVE-2024-57908 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: |
