| Subject: CVE-2024-42086: iio: chemical: bme680: Fix overflows in compensate() functions |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| iio: chemical: bme680: Fix overflows in compensate() functions |
| |
| There are cases in the compensate functions of the driver that |
| there could be overflows of variables due to bit shifting ops. |
| These implications were initially discussed here [1] and they |
| were mentioned in log message of Commit 1b3bd8592780 ("iio: |
| chemical: Add support for Bosch BME680 sensor"). |
| |
| [1]: https://lore.kernel.org/linux-iio/20180728114028.3c1bbe81@archlinux/ |
| |
| The Linux kernel CVE team has assigned CVE-2024-42086 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: |
