FKIE_CVE-2017-5967

Vulnerability from fkie_nvd - Published: 2017-02-14 06:59 - Updated: 2026-06-17 01:21
Severity
4.0 (Medium) - CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N
Summary
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.
