| Description: | 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 __blk_add_trace 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 kernel_read_file function in fs/exec.c allows to cause a denial of service (CVE-2019-8980)
kernel: unprivileged users able to create RAW sockets in AF_IEEE802154 network protocol. (CVE-2019-17053)
kernel: unprivileged users able to create RAW sockets in AF_ISDN network protocol. (CVE-2019-17055)
kernel: integer overflow in tcp_ack_update_rtt in net/ipv4/tcp_input.c (CVE-2019-18805)
kernel: information leak bug caused by a malicious USB device in the drivers/net/can/usb/peak_usb/pcan_usb_core.c driver (CVE-2019-19534)
kernel: some ipv6 protocols not encrypted over ipsec tunnel. (CVE-2020-1749)
Kernel: net: using kernel space address bits to derive IP ID may potentially break KASLR (CVE-2019-10639)
kernel: An out-of-bounds read in drivers/scsi/qedi/qedi_dbg.c leading to crash or information disclosure (CVE-2019-15090)
kernel: a NULL pointer dereference in drivers/net/wireless/ath/ath10k/usb.c leads to a crash (CVE-2019-15099)
kernel: Null pointer dereference in the sound/usb/line6/pcm.c (CVE-2019-15221)
kernel: Two memory leaks in the mwifiex_pcie_init_evt_ring() function in drivers/net/wireless/marvell/mwifiex/pcie.c allows for a DoS (CVE-2019-19057)
kernel: Memory leaks in drivers/net/wireless/ath/ath9k/htc_hst.c in the Linux kernel (DOS) (CVE-2019-19073)
kernel: a memory leak in the ath9k management function in allows local DoS (CVE-2019-19074)
kernel: when cpu.cfs_quota_us is used allows attackers to cause a denial of service against non-cpu-bound applications (CVE-2019-19922)

Bug Fix(es):
RT: update RT source tree to the RHEL-8.2 tree (BZ#1708716)
KVM-RT guest fails boot with emulatorsched (BZ#1712781)
8 vCPU guest need max latency < 20 us with stress [RT-8.2] (BZ#1757165)
Request nx_huge_pages=N as default value to avoid kvm-rt guest large latency spike [rt-8] (BZ#1788352)
