An update for systemd is now available for Red Hat Enterprise Linux 8.6
 Extended Update Support.

Red Hat Product Security has rated this update as having a security impact of
 Moderate. 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.

The systemd packages contain systemd, a system and service manager for Linux,
 compatible with the SysV and LSB init scripts. It provides aggressive parallelism capabilities, uses socket and D-Bus activation for starting services, offers on-demand starting of daemons, and keeps track of processes using Linux cgroups. In addition, it supports snapshotting and restoring of the system state, maintains mount and automount points, and implements an elaborate transactional dependency-based service control logic. It can also work as a drop-in replacement for sysvinit.

Security Fix(es):

* systemd: buffer overrun in format_timespan() function (CVE-2022-3821)

* systemd: local information leak due to systemd-coredump not respecting
 fs.suid_dumpable kernel setting (CVE-2022-4415)

* systemd: privilege escalation via the less pager (CVE-2023-26604)
