Containers failed to start due to memory allocation failure in ip_set_net_init().Kernel module 'ip_set' tried to allocate physically contiguous memory areas for its array of pointers to 'ip_set' structures in ip_set_net_init(). If large enough maximum number of IP sets was requested from the user space, memory allocation would fail. Containers would fail to start as a result.
Out-of-bounds access in show_timer() function.The implementation of timer_create system call in the Linux kernel before 4.14.8 doesn't properly validate the sigevent::sigev_notify field, which leads to out-of-bounds access in the show_timer function (called when /proc/$PID/timers is read). This allows userspace applications to read arbitrary kernel memory (on a kernel built with CONFIG_POSIX_TIMERS and CONFIG_CHECKPOINT_RESTORE).https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2017-18344
