Moderate: systemd security, bug fix, and enhancement update

Other sources

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: systemd: Arbitrary code execution or Denial of Service via spurious IPC API call data (CVE-2026-29111) Bug Fix(es) and Enhancement(s): spec: systemd build fails due to rename of rhel-net-naming-sysattrs upstream [rhel-9.6.z] (JIRA:RHEL-150627) fstab-generator: addswap() does not support netdev so booting when swap is over iscsi does not take. [rhel-9.6.z] (JIRA:RHEL-166184) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
