The vulnerability of the functions get_perf_level_count() and cppc_get_cpu_power() in the driver/cpufreq/cppc_cpufreq.c module, a frequency scaling driver for Linux processors, allows a hacker to trigger a service failure.

The vulnerability of the getperflevelcount and cppcgetcpupower functions in the drivers/cpufreq/cppccpufreq.c driver for scaling kernel frequency in Linux operating systems is related to copying buffers without checking their size a classic buffer overflow attack. Exploiting this vulnerability...
