Hi,

You are receiving an AlmaLinux Security update email because you subscribed to receive errata
notifications from AlmaLinux.

AlmaLinux: 9
Type: Security
Severity: Moderate
Release date: 2025-12-04

Summary:

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-coredump: race condition that allows a local attacker to crash a SUID program and gain
read access to the resulting core dump (CVE-2025-4598)


For more details about the security issue(s), including the impact, a CVSS score, acknowledgments,
