CVE-2026-40224: Incorrect Authorization

In systemd 259 before 260, there is local privilege escalation in systemd-machined because varlink can be used to reach the root namespace...

CVE-2026-40227: Comparison Using Wrong Factors

In systemd 260 before 261, a local unprivileged user can trigger an assert via an IPC API call with an array or map that has a null element...

CVE-2026-40226: Use of Less Trusted Source

In nspawn in systemd 233 through 259 before 260, an escape-to-host action can occur via a crafted optional config file...

PT-2026-31933

Name of the Vulnerable Software and Affected Versions systemd versions 259 through 259 Description A local privilege escalation exists in systemd-machined. This occurs because varlink, a lightweight communication protocol, can be used to reach the root namespace, allowing a local attacker to gain...

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: Privilege escalation via improper access control in RegisterMachine D-Bus method

A flaw was found in systemd. The systemd-machined service contains an Improper Access Control vulnerability due to insufficient validation of the class parameter in the RegisterMachine D-Bus Desktop Bus method. A local unprivileged user can exploit this by attempting to register a machine with a...

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-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: Denial of Service via malicious IPC API call with null element

A flaw was found in systemd. A local unprivileged user can exploit this vulnerability by making an Inter-Process Communication IPC API call with a specially crafted array or map containing a null element. This can trigger an assert, leading to a Denial of Service DoS condition, which makes the...

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: 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 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...

SUSE CVE-2026-39314

OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. In versions 2.4.16 and prior, an integer underflow vulnerability in ppdCreateFromIPP cups/ppd-cache.c allows any unprivileged local user to crash the cupsd root process by supplying a negative...
