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 Enterprise Linux ComputeNode EUS (v. 7.6) – noarch, x86_64
Red Hat Enterprise Linux ComputeNode Optional EUS (v. 7.6) – x86_64
Red Hat Enterprise Linux Server EUS (v. 7.6) – noarch, ppc64, ppc64le, s390x, x86_64
Red Hat Enterprise Linux Server Optional EUS (v. 7.6) – ppc64, ppc64le, x86_64

3. Description:

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

Security Fix(es):

* kernel: Count overflow in FUSE request leading to use-after-free issues.
(CVE-2019-11487)

* Kernel: KVM: OOB memory access via mmio ring buffer (CVE-2019-14821)

* Kernel: vfio: access to disabled MMIO space of some devices may lead to
DoS scenario (CVE-2020-12888)

* kernel: denial of service via ioctl call in network tun handling
(CVE-2018-7191)

* kernel: usb: missing size check in the __usb_get_extra_descriptor()
leading to DoS (CVE-2018-20169)

* kernel: perf_event_open() and execve() race in setuid programs allows a
data leak (CVE-2019-3901)
