The following security issues were fixed:
CVE-2019-11487: The Linux kernel allowed page->_refcount reference count
 overflow, with resultant use-after-free issues, if about 140 GiB of RAM
 exists. This is related to fs/fuse/dev.c, fs/pipe.c, fs/splice.c,
 include/linux/mm.h, include/linux/pipe_fs_i.h, kernel/trace/trace.c,
 mm/gup.c, and mm/hugetlb.c. It can occur with FUSE requests
 (bsc#1133191).

CVE-2018-5390: Linux kernel could be forced to make very expensive calls
 to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming
 packet which can lead to a denial of service (bsc#1102682).");
