CVE-2020-27825: Fixed a race in the trace_open and buffer resize calls (bsc#1179960).

CVE-2020-0466: Fixed a use-after-free due to a logic error in do_epoll_ctl and ep_loop_check_proc of eventpoll.c (bnc#1180031).

CVE-2020-27068: Fixed an out-of-bounds read due to a missing bounds check in the nl80211_policy policy of nl80211.c (bnc#1180086).

CVE-2020-0444: Fixed a bad kfree due to a logic error in audit_data_to_entry (bnc#1180027).

CVE-2020-0465: Fixed multiple missing bounds checks in hid-multitouch.c that could have led to local privilege escalation (bnc#1180029).

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-2020-27777: 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-2020-29373: Fixed an unsafe handling of the root directory during path lookups in fs/io_uring.c (bnc#1179434).

CVE-2020-11668: Fixed the mishandling of invalid descriptors in the Xirlink camera USB driver (bnc#1168952).
