CVE-2017-2618: Off-by-one Error

A flaw was found in the Linux kernel's handling of clearing SELinux attributes on /proc/pid/attr files before 4.9.10. An empty null write to this file can crash the system by causing the system to attempt to access unmapped kernel memory...

CVE-2017-18344

The timercreate syscall implementation in kernel/time/posix-timers.c in the Linux kernel before 4.14.8 doesn't properly validate the sigevent-sigevnotify field, which leads to out-of-bounds access in the showtimer function called when /proc/$PID/timers is read. This allows userspace applications ...
