CVE-2024-50178

Estado: ModificadaMedia (5.5)—

In the Linux kernel, the following vulnerability has been resolved:

cpufreq: loongson3: Use raw_smp_processor_id() in do_service_request()

Use raw_smp_processor_id() instead of plain smp_processor_id() in do_service_request(), otherwise we may get some errors with the driver enabled:

Detalles técnicos trazas, registros y código del informe original
 BUG: using smp_processor_id() in preemptible [00000000] code: (udev-worker)/208
 caller is loongson3_cpufreq_probe+0x5c/0x250 [loongson3_cpufreq]
