The following security issues were fixed:
CVE-2019-3846: A flaw that allowed an attacker to corrupt memory and
 possibly escalate privileges was found in the mwifiex kernel module
 while connecting to a malicious wireless network (bsc#1136446).

CVE-2019-11477: A sequence of SACKs may have been crafted by a remote
 attacker such that one can trigger an integer overflow, leading to a
 kernel panic. (bsc#1137586).

CVE-2019-11478: It was possible to send a crafted sequence of SACKs
 which would fragment the TCP retransmission queue. A remote attacker may
 have been able to further exploit the fragmented queue to cause an
 expensive linked-list walk for subsequent SACKs received for that same
 TCP connection. (bsc#1137586)

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).");
