(CVE-2019-11487)

* Kernel: KVM: OOB memory access via mmio ring buffer (CVE-2019-14821)

* Kernel: vfio: access to disabled MMIO space of some devices may lead to
DoS scenario (CVE-2020-12888)

* kernel: denial of service via ioctl call in network tun handling
(CVE-2018-7191)

* kernel: usb: missing size check in the __usb_get_extra_descriptor()
leading to DoS (CVE-2018-20169)

* kernel: perf_event_open() and execve() race in setuid programs allows a
data leak (CVE-2019-3901)

* kernel: use-after-free in arch/x86/lib/insn-eval.c (CVE-2019-13233)

* kernel: memory leak in register_queue_kobjects() in net/core/net-sysfs.c
leads to denial of service (CVE-2019-15916)

* kernel: powerpc: incomplete Spectre-RSB mitigation leads to information
exposure (CVE-2019-18660)

For more details about the security issue(s), including the impact, a CVSS
score, acknowledgments, and other related information, refer to the CVE
page(s) listed in the References section.

Bug Fix(es):
