CVE-2021-33910 5 Debian, Fedoraproject, Netapp and 2 more 8 Debian Linux, Fedora, Hci Management Node and 5 more 2025-06-09 5.5 Medium
basic/unit-name.c in systemd prior to 246.15, 247.8, 248.5, and 249.1 has a Memory Allocation with an Excessive Size Value (involving strdupa and alloca for a pathname controlled by a local attacker) that results in an operating system crash.
CVE-2020-13776 4 Fedoraproject, Netapp, Redhat and 1 more 6 Fedora, Active Iq Unified Manager, Solidfire \& Hci Management Node and 3 more 2025-06-09 6.7 Medium
systemd through v245 mishandles numerical usernames such as ones composed of decimal digits or 0x followed by hex digits, as demonstrated by use of root privileges when privileges of the 0x0 user account were intended. NOTE: this issue exists because of an incomplete fix for CVE-2017-1000082.
CVE-2019-20386 6 Canonical, Fedoraproject, Netapp and 3 more 9 Ubuntu Linux, Fedora, Active Iq Unified Manager and 6 more 2025-06-09 5.1 Medium
An issue was discovered in button_open in login/logind-button.c in systemd before 243. When executing the udevadm trigger command, a memory leak may occur.
CVE-2018-6954 3 Canonical, Opensuse, Systemd Project 3 Ubuntu Linux, Leap, Systemd 2025-06-09 7.8 High
systemd-tmpfiles in systemd through 237 mishandles symlinks present in non-terminal path components, which allows local users to obtain ownership of arbitrary files via vectors involving creation of a directory and a file under that directory, and later replacing that directory with a symlink. This occurs even if the fs.protected_symlinks sysctl is turned on.
CVE-2018-15688 4 Canonical, Debian, Redhat and 1 more 10 Ubuntu Linux, Debian Linux, Enterprise Linux and 7 more 2025-06-09 8.8 High
A buffer overflow vulnerability in the dhcp6 client of systemd allows a malicious dhcp6 server to overwrite heap memory in systemd-networkd. Affected releases are systemd: versions up to and including 239.
CVE-2018-15687 2 Canonical, Systemd Project 2 Ubuntu Linux, Systemd 2025-06-09 7.0 High
A race condition in chown_one() of systemd allows an attacker to cause systemd to set arbitrary permissions on arbitrary files. Affected releases are systemd versions up to and including 239.
CVE-2018-15686 5 Canonical, Debian, Oracle and 2 more 10 Ubuntu Linux, Debian Linux, Communications Cloud Native Core Network Function Cloud Native Environment and 7 more 2025-06-09 7.8 High
A vulnerability in unit_deserialize of systemd allows an attacker to supply arbitrary state across systemd re-execution via NotifyAccess. This can be used to improperly influence systemd execution and possibly lead to root privilege escalation. Affected releases are systemd versions up to and including 239.
CVE-2013-4392 1 Systemd Project 1 Systemd 2025-06-09 5 Medium
systemd, when updating file permissions, allows local users to change the permissions and SELinux security contexts for arbitrary files via a symlink attack on unspecified files.
CVE-2020-1712 3 Debian, Redhat, Systemd Project 8 Debian Linux, Ceph Storage, Discovery and 5 more 2025-06-09 7.8 High
A heap use-after-free vulnerability was found in systemd before version v245-rc1, where asynchronous Polkit queries are performed while handling dbus messages. A local unprivileged attacker can abuse this flaw to crash systemd services or potentially execute code and elevate their privileges, by sending specially crafted dbus messages.
CVE-2018-16864 5 Canonical, Debian, Oracle and 2 more 16 Ubuntu Linux, Debian Linux, Communications Session Border Controller and 13 more 2025-06-09 7.8 High
An allocation of memory without limits, that could result in the stack clashing with another memory region, was discovered in systemd-journald when a program with long command line arguments calls syslog. A local attacker may use this flaw to crash systemd-journald or escalate his privileges. Versions through v240 are vulnerable.
CVE-2018-16865 5 Canonical, Debian, Oracle and 2 more 16 Ubuntu Linux, Debian Linux, Communications Session Border Controller and 13 more 2025-06-09 7.8 High
An allocation of memory without limits, that could result in the stack clashing with another memory region, was discovered in systemd-journald when many entries are sent to the journal socket. A local attacker, or a remote one if systemd-journal-remote is used, may use this flaw to crash systemd-journald or execute code with journald privileges. Versions through v240 are vulnerable.
CVE-2019-3843 5 Canonical, Fedoraproject, Netapp and 2 more 9 Ubuntu Linux, Fedora, Cn1610 and 6 more 2025-06-09 7.8 High
It was discovered that a systemd service that uses DynamicUser property can create a SUID/SGID binary that would be allowed to run as the transient service UID/GID even after the service is terminated. A local attacker may use this flaw to access resources that will be owned by a potentially different service in the future, when the UID/GID will be recycled.
CVE-2019-3844 4 Canonical, Netapp, Redhat and 1 more 8 Ubuntu Linux, Cn1610, Cn1610 Firmware and 5 more 2025-06-09 7.8 High
It was discovered that a systemd service that uses DynamicUser property can get new privileges through the execution of SUID binaries, which would allow to create binaries owned by the service transient group with the setgid bit set. A local attacker may use this flaw to access resources that will be owned by a potentially different service in the future, when the GID will be recycled.
CVE-2019-3842 4 Debian, Fedoraproject, Redhat and 1 more 5 Debian Linux, Fedora, Enterprise Linux and 2 more 2025-06-09 7.0 High
In systemd before v242-rc4, it was discovered that pam_systemd does not properly sanitize the environment before using the XDG_SEAT variable. It is possible for an attacker, in some particular configurations, to set a XDG_SEAT environment variable which allows for commands to be checked against polkit policies using the "allow_active" element rather than "allow_any".
CVE-2018-16866 5 Canonical, Debian, Netapp and 2 more 26 Ubuntu Linux, Debian Linux, Active Iq Performance Analytics Services and 23 more 2025-06-09 3.3 Low
An out of bounds read was discovered in systemd-journald in the way it parses log messages that terminate with a colon ':'. A local attacker can use this flaw to disclose process memory data. Versions from v221 to v239 are vulnerable.
CVE-2022-4415 2 Redhat, Systemd Project 3 Enterprise Linux, Rhel Eus, Systemd 2025-05-05 5.5 Medium
A vulnerability was found in systemd. This security flaw can cause a local information leak due to systemd-coredump not respecting the fs.suid_dumpable kernel setting.
CVE-2018-20839 2 Netapp, Systemd Project 5 Cn1610, Cn1610 Firmware, Snapprotect and 2 more 2025-05-05 4.3 Medium
systemd 242 changes the VT1 mode upon a logout, which allows attackers to read cleartext passwords in certain circumstances, such as watching a shutdown, or using Ctrl-Alt-F1 and Ctrl-Alt-F2. This occurs because the KDGKBMODE (aka current keyboard mode) check is mishandled.
CVE-2022-3821 3 Fedoraproject, Redhat, Systemd Project 4 Fedora, Enterprise Linux, Rhel Eus and 1 more 2025-05-02 5.5 Medium
An off-by-one Error issue was discovered in Systemd in format_timespan() function of time-util.c. An attacker could supply specific values for time and accuracy that leads to buffer overrun in format_timespan(), leading to a Denial of Service.
CVE-2022-45873 3 Fedoraproject, Redhat, Systemd Project 3 Fedora, Enterprise Linux, Systemd 2025-04-25 5.5 Medium
systemd 250 and 251 allows local users to achieve a systemd-coredump deadlock by triggering a crash that has a long backtrace. This occurs in parse_elf_object in shared/elf-util.c. The exploitation methodology is to crash a binary calling the same function recursively, and put it in a deeply nested directory to make its backtrace large enough to cause the deadlock. This must be done 16 times when MaxConnections=16 is set for the systemd/units/systemd-coredump.socket file.
CVE-2017-9445 1 Systemd Project 1 Systemd 2025-04-20 7.5 High
In systemd through 233, certain sizes passed to dns_packet_new in systemd-resolved can cause it to allocate a buffer that's too small. A malicious DNS server can exploit this via a response with a specially crafted TCP payload to trick systemd-resolved into allocating a buffer that's too small, and subsequently write arbitrary data beyond the end of it.
