====================================================================
1. Summary:

An update for kernel is now available for Red Hat Enterprise Linux 8.

Red Hat Product Security has rated this update as having a security impact
of Important. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available for each vulnerability
from the CVE link(s) in the References section.

2. Relevant releases/architectures:

Red Hat CodeReady Linux Builder (v. 8) - aarch64, ppc64le, x86_64
Red Hat Enterprise Linux BaseOS (v. 8) - aarch64, noarch, ppc64le, s390x, x86_64

3. Description:

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

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)
