Description OSIDB Bzimport 2024-11-08 13:46:44 UTC 
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:
