| Subject: CVE-2024-38615: cpufreq: exit() callback is optional |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| cpufreq: exit() callback is optional |
| |
| The exit() callback is optional and shouldn't be called without checking |
| a valid pointer first. |
| |
| Also, we must clear freq_table pointer even if the exit() callback isn't |
| present. |
| |
| The Linux kernel CVE team has assigned CVE-2024-38615 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: |
