Denial Of Service

Linux kernel is vulnerable to denial of service. Linux fair scheduler has a use-after-free in show_numa_stats() because NUMA fault statistics are inappropriately freed. A flaw was found in the Linux kernels implementation of displaying NUMA statistics, where displaying the scheduler statistics could trigger a use-after-free in show_numa_stats() and display the kernel memory to userspace. The highest threat from this vulnerability is to system availability.
