RHSA-2020:1567: Important: kernel-rt security, bug fix, and enhancement update

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.Security Fix(es): kernel: use-after-free in blkaddtrace in kernel/trace/blktrace.c (CVE-2019-19768) kernel: nfs: NULL pointer dereference due to an anomalized NFS message sequence (CVE-2018-16871) kernel: memory leak in the kernelreadfile function in fs/exec.c allows to cause a denial of service (CVE-2019-8980) kernel: unprivileged users able to create RAW sockets in AFIEEE802154 network protocol. (CVE-2019-17053) kernel: unprivileged users able to create RAW sockets in AFISDN network protocol. (CVE-2019-17055) kernel: integer overflow in tcpackupdatertt in net/ipv4/tcpinput.c (CVE-2019-18805) kernel: information leak bug caused by a malicious USB device in the drivers/net/can/usb/peakusb/pcanusbcore.c driver (CVE-2019-19534) kernel: some ipv6 protocols not encrypted over ipsec tunnel.
