Title: Linux Kernel の time サブシステムにおける実際の PID 値を取得される脆弱性
Summary: Linux Kernel の time サブシステムには、CONFIG_TIMER_STATS が有効になっている場合、kernel/time/timer_list.c の print_timer 関数、および kernel/time/timer.c の __timer_stats_timer_set_start_info 関数に関する処理に不備があるため、(PID 名前空間内の PID 値と区別されるような) 実際の PID 値を取得される脆弱性が存在します。

  descriptionThe time subsystem in the Linux kernel through 4.9.9, when CONFIG_TIMER_STATS is enabled, allows local users to discover real PID values (as distinguished from PID values inside a PID namespace) by reading the /proc/timer_list file, related to the print_timer function in kernel/time/timer_list.c and the __timer_stats_timer_set_start_info function in kernel/time/timer.c.
