Detailsinfo

A vulnerability classified as critical was found in Linux Kernel up to 6.15-rc3. This vulnerability affects the function scpi_cpufreq_get_rate of the component cpufreq. The manipulation with an unknown input leads to a null pointer dereference vulnerability. The CWE definition for the vulnerability is CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. As an impact it is known to affect availability. CVE summarizes:

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 advisory is shared for download at git.kernel.org. This vulnerability was named CVE-2025-37829 since 04/16/2025. There are known technical details, but no exploit is available.
