3. Description:

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

Security Fix(es):

* kernel: nfs: use-after-free in svc_process_common() (CVE-2018-16884)

* kernel: insufficient input validation in kernel mode driver in Intel i915
graphics leads to privilege escalation (CVE-2019-11085)

* kernel: nfs: NULL pointer dereference due to an anomalized NFS message
sequence (CVE-2018-16871)

* kernel: use-after-free in drivers/char/ipmi/ipmi_si_intf.c,
ipmi_si_mem_io.c, ipmi_si_port_io.c (CVE-2019-11811)

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.
