systemd

About this tag
The systemd tag on WindowsForum.com covers security vulnerabilities and integrity topics related to the Linux init system and service manager. Recent discussions include CVE-2026-4105, a privilege escalation in systemd-machined allowing local root access, and CVE-2022-4415, a core dump leak affecting setuid processes. Microsoft's Azure Linux is noted as potentially affected by these CVEs. Additionally, the tag covers Amutable, a startup co-founded by systemd creator Lennart Poettering, focusing on deterministic Linux integrity from build to runtime. These threads are relevant for Linux system administrators and security professionals monitoring systemd-related threats and developments.

  2. CVE-2022-4415: Systemd coredump leak and Azure Linux attestations

    The systemd component that collects and stores core dumps — systemd‑coredump — was found in January 2023 to ignore the kernel’s fs.suid_dumpable setting, allowing core files for setuid/setgid (privileged) processes to be produced and, under some configurations, read by non‑privileged users. That...

  3. CVE-2025-4598 Systemd Coredump: Azure Linux Attestation Explained

    The short answer is: No — Azure Linux is the only Microsoft product Microsoft has publicly attested today to include the upstream systemd-coredump component implicated by CVE‑2025‑4598, but that attestation is product‑scoped, not an exclusivity guarantee. Any Microsoft artifact that ships or...
