| CVE-2026-40224 | HIGH7.3 | In systemd 259 before 260, there is local privilege escalation in systemd-machined because varlink can be used to reach the root namespace. | 10/04/2026 |
| CVE-2026-40223 | MEDIUM5.5 | In systemd 258 before 260, a local unprivileged user can trigger an assert when a Delegate=yes and User=<unset> unit exists and is running. | 10/04/2026 |
| CVE-2026-29111 | MEDIUM5.5 | systemd, a system and service manager, (as PID 1) hits an assert and freezes execution when an unprivileged IPC API call is made with spurious data. On version v249 and older the effect is not an assert, but stack overwriting, with the attacker controlled content. From version v250 and newer this is not possible as the | 23/03/2026 |
| CVE-2025-4598 | MEDIUM4.7 | A vulnerability was found in systemd-coredump. This flaw allows an attacker to force a SUID process to crash and replace it with a non-SUID binary to access the original's privileged process coredump, allowing the attacker to read sensitive data, such as /etc/shadow content, loaded by the original process.
A SUID bina | 30/05/2025 |
| CVE-2023-7008 | MEDIUM5.9 | A vulnerability was found in systemd-resolved. This issue may allow systemd-resolved to accept records of DNSSEC-signed domains even when they have no signature, allowing man-in-the-middles (or the upstream DNS resolver) to manipulate records. | 23/12/2023 |
| CVE-2023-31439 | MEDIUM5.3 | An issue was discovered in systemd 253. An attacker can modify the contents of past events in a sealed log file and then adjust the file such that checking the integrity shows no error, despite modifications. NOTE: the vendor reportedly sent "a reply denying that any of the finding was a security vulnerability." | 13/06/2023 |
| CVE-2023-31438 | MEDIUM5.3 | An issue was discovered in systemd 253. An attacker can truncate a sealed log file and then resume log sealing such that checking the integrity shows no error, despite modifications. NOTE: the vendor reportedly sent "a reply denying that any of the finding was a security vulnerability." | 13/06/2023 |
| CVE-2023-31437 | MEDIUM5.3 | An issue was discovered in systemd 253. An attacker can modify a sealed log file such that, in some views, not all existing and sealed log messages are displayed. NOTE: the vendor reportedly sent "a reply denying that any of the finding was a security vulnerability." | 13/06/2023 |
| CVE-2023-26604 | HIGH7.8 | systemd before 247 does not adequately block local privilege escalation for some Sudo configurations, e.g., plausible sudoers files in which the "systemctl status" command may be executed. Specifically, systemd does not set LESSSECURE to 1, and thus other programs may be launched from the less program. This presents a | 03/03/2023 |
| CVE-2022-4415 | MEDIUM5.5 | 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. | 11/01/2023 |
| CVE-2022-45873 | MEDIUM5.5 | 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 it | 23/11/2022 |
| CVE-2022-3821 | MEDIUM5.5 | 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. | 08/11/2022 |
| CVE-2022-2526 | CRITICAL9.8 | A use-after-free vulnerability was found in systemd. This issue occurs due to the on_stream_io() function and dns_stream_complete() function in 'resolved-dns-stream.c' not incrementing the reference counting for the DnsStream object. Therefore, other functions and callbacks called can dereference the DNSStream object, | 09/09/2022 |
| CVE-2021-3997 | MEDIUM5.5 | A flaw was found in systemd. An uncontrolled recursion in systemd-tmpfiles may lead to a denial of service at boot time when too many nested directories are created in /tmp. | 23/08/2022 |
| CVE-2021-33910 | MEDIUM5.5 | 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. | 20/07/2021 |
| CVE-2020-13529 | MEDIUM6.1 | An exploitable denial-of-service vulnerability exists in Systemd 245. A specially crafted DHCP FORCERENEW packet can cause a server running the DHCP client to be vulnerable to a DHCP ACK spoofing attack. An attacker can forge a pair of FORCERENEW and DCHP ACK packets to reconfigure the server. | 10/05/2021 |
