| Subject: CVE-2025-37829: cpufreq: scpi: Fix null-ptr-deref in scpi_cpufreq_get_rate() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| cpufreq: scpi: Fix null-ptr-deref in scpi_cpufreq_get_rate() |
| |
| cpufreq_cpu_get_raw() can return NULL when the target CPU is not present |
| in the policy->cpus mask. scpi_cpufreq_get_rate() does not check for |
| this case, which results in a NULL pointer dereference. |
| |
| The Linux kernel CVE team has assigned CVE-2025-37829 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: |
