Summary
systemd vulnerabilities
Details

It was discovered that systemd-homed did not properly verify the signature of home records. A local attacker could possibly use this issue to add arbitrary system groups to a logged-in user and gain elevated privileges. (CVE-2026-16742)

It was discovered that systemd-machined incorrectly handled certain polkit authorization checks. A local attacker could possibly use this issue to terminate arbitrary processes, including privileged ones. This issue only affected Ubuntu 26.04 LTS. (CVE-2026-15060)

It was discovered that systemd-oomd did not properly validate certain IPC requests. A local attacker could possibly use this issue to terminate arbitrary processes. (CVE-2026-15059)
