CVE-2017-5967

Published: 14 February 2017

The 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.

From the Ubuntu security team

It was discovered that the timer stats implementation in the Linux kernel allowed the discovery of a real PID value while inside a PID namespace. A local attacker could use this to expose sensitive information.

Priority

Low
