| Subject: CVE-2024-40933: iio: temperature: mlx90635: Fix ERR_PTR dereference in mlx90635_probe() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| iio: temperature: mlx90635: Fix ERR_PTR dereference in mlx90635_probe() |
| |
| When devm_regmap_init_i2c() fails, regmap_ee could be error pointer, |
| instead of checking for IS_ERR(regmap_ee), regmap is checked which looks |
| like a copy paste error. |
| |
| The Linux kernel CVE team has assigned CVE-2024-40933 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: |
| https://git.kernel.org/stable/c/5a5595ae8cc7cdaa1a10b56a26ddbe3429245c6c |
