3. Description:

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

Security Fix(es):

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

* kernel: local attacker can trigger multiple use-after-free conditions
results in privilege escalation (CVE-2019-15239)

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.
