Security Fix(es):

* glib: integer overflow in g_bytes_new function on 64-bit platforms due to
an implicit cast from 64 bits to 32 bits (CVE-2021-27219)

* kernel: userspace applications can misuse the KVM API to cause a write of
16 bytes at an offset up to 32 GB from vcpu->run (CVE-2021-3501)

* polkit: local privilege escalation using
polkit_system_bus_name_get_creds_sync() (CVE-2021-3560)

* hw: vt-d related privilege escalation (CVE-2020-24489)

For more details about the security issue(s), including the impact, a CVSS
score, and other related information, refer to the CVE page(s) listed in
the References section.

Bug Fix(es):

* Previously, systemtap dependencies were not included in the RHV-H
channel. Therefore, systemtap could not be installed.
In this release, the systemtap dependencies have been included in the
channel, resolving the issue. (BZ#1903997)
