Description
The perf_cpu_time_max_percent_handler function in kernel/events/core.c in the Linux kernel before 4.11 allows local users to cause a denial of service (integer overflow) or possibly have unspecified other impact via a large value, as demonstrated by an incorrect sample-rate calculation.
A vulnerability was found in the Linux kernel's kernel/events/core.c:perf_cpu_time_max_percent_handler() function. Local privileged users could exploit this flaw to cause a denial of service due to integer overflow or possibly have unspecified other impact.
