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
