conntrack netlink configuration that could cause a denial of service or
trigger the use of incorrect protocol numbers in
ctnetlink_parse_tuple_filter (bnc#1176395).
- CVE-2020-14390: Fixed an out-of-bounds memory write leading to memory
corruption or a denial of service when changing screen size
(bnc#1176235).

rbd devices, which could have been leveraged by local attackers to map
or unmap rbd block devices (bsc#1176482).

dropping the references (bsc#1176011).

check in the nl80211_policy policy of nl80211.c (bnc#1180086).
- CVE-2020-27777: Fixed a privilege escalation in the Run-Time Abstraction
Services (RTAS) interface, affecting guests running on top of PowerVM or
KVM hypervisors (bnc#1179107).
- CVE-2020-27786: Fixed an out-of-bounds write in the MIDI implementation
(bnc#1179601).
- CVE-2020-29660: Fixed a locking inconsistency in the tty subsystem that
may have allowed a read-after-free attack against TIOCGSID (bnc#1179745).
- CVE-2020-29661: Fixed a locking issue in the tty subsystem that allowed
a use-after-free attack against TIOCSPGRP (bsc#1179745).
- CVE-2020-28974: Fixed a slab-out-of-bounds read in fbcon which could
have been used by local attackers to read privileged information or
potentially crash the kernel (bsc#1178589).
- CVE-2020-28915: Fixed a buffer over-read in the fbcon code which could
have been used by local attackers to read kernel memory (bsc#1178886).

(bsc#1178182).
- CVE-2020-25285: A race condition between hugetlb sysctl handlers in
mm/hugetlb.c could be used by local attackers to corrupt memory, cause a
NULL pointer dereference, or possibly have unspecified other impact
