CVE-2026-40228: Incorrect Resource Transfer Between Spheres

In systemd 259, systemd-journald can send ANSI escape sequences to the terminals of arbitrary users when a "logger -p emerg" command is executed, if ForwardToWall=yes is set...

openSUSE 16 Security Update : systemd (openSUSE-SU-2026:20471-1)

The remote openSUSE 16 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:20471-1 advisory. Update to systemd v257.13: Security issues: - CVE-2026-4105: privilege escalation due to improper access control in RegisterMachine D-Bus method...

systemd: udev in systemd: Privilege escalation via malicious hardware devices and unsanitized kernel output

A flaw was found in udev in systemd. A local user with access to malicious hardware devices can exploit this vulnerability. By providing unsanitized kernel output, the flaw allows for local root execution, leading to privilege escalation...

systemd: systemd: Arbitrary code execution or Denial of Service via spurious IPC API call data

A flaw was found in systemd, a system and service manager. An unprivileged user can exploit this vulnerability by making an Inter-Process Communication IPC API call with spurious data. In older versions v249 and earlier, this can lead to stack overwriting with attacker-controlled content,...

systemd: systemd: Local unprivileged user can cause Denial of Service

A flaw was found in systemd, a core component of Linux operating systems. A local user, without special privileges, can exploit this vulnerability. By manipulating a specific systemd unit configuration where delegation is enabled and the user is not set, the user can trigger an internal error,...

systemd: systemd-journald: Unintended output to user terminals via logger command

A flaw was found in systemd-journald. When the ForwardToWall=yes configuration is enabled, a local user who executes a logger -p emerg command can cause systemd-journald to send ANSI escape sequences to the terminals of other arbitrary users. This can lead to unintended output appearing on user...

systemd: systemd-machined: Local privilege escalation via varlink

A flaw was found in systemd-machined, a component of systemd. A local attacker can exploit a vulnerability related to how varlink interacts with the root namespace. This can lead to local privilege escalation, allowing the attacker to gain elevated access on the system...

systemd: systemd nspawn: Escape-to-host action via crafted config file

A flaw was found in nspawn, a container runtime environment within systemd. A local attacker or a process within an nspawn container could exploit this vulnerability by using a specially crafted optional configuration file. This could allow the attacker to escape the container's isolation and...
