The following security issues were fixed:
CVE-2019-9213: Expand_downwards in mm/mmap.c lacked a check for the mmap
minimum address, which made it easier for attackers to exploit kernel
NULL pointer dereferences on non-SMAP platforms. This is related to a
capability check for the wrong task (bsc#1128378).
CVE-2019-7221: Fixed a user-after-free vulnerability in the KVM
hypervisor related to the emulation of a preemption timer, allowing an
guest user/process to crash the host kernel. (bsc#1124734).
CVE-2018-5391: The Linux kernel was vulnerable to a denial of service
attack with low rates of specially modified packets targeting IP
fragment re-assembly. An attacker might have caused a denial of service
condition by sending specially crafted IP fragments. Various
vulnerabilities in IP fragmentation have been discovered and fixed over
the years. The current vulnerability (CVE-2018-5391) became exploitable
in the Linux kernel with the increase of the IP fragment reassembly
queue size (bsc#1103098).");
