| Subject: CVE-2024-39466: thermal/drivers/qcom/lmh: Check for SCM availability at probe |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| thermal/drivers/qcom/lmh: Check for SCM availability at probe |
| |
| Up until now, the necessary scm availability check has not been |
| performed, leading to possible null pointer dereferences (which did |
| happen for me on RB1). |
| |
| Fix that. |
| |
| The Linux kernel CVE team has assigned CVE-2024-39466 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: |
