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

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)
* RT: Add rpm Provide of 'kernel' to indicate that this is a kernel package (BZ#1796284)
* [RHEL8] RT kernel signed by test certificate and not Red Hat Secure Boot (BZ#1806871)
Enhancement(s):
* update to the upstream 5.x RT patchset (BZ#1680161)

Quick Help

Unknown Tests
There is a hardcoded maximum limit for number of tests displayed for a definition. For a small number of oval definitions, about ~1% of all, hundreds of test have been defined. This causes the pages to grow in size, exceed even 1mb, and they are unsuitable for display in a web page. So they are not displayed.Please refer to the xml definition files if you really want to view them.
