[NEW] [medium] systemd: Multiple vulnerabilities

mediumCVE-2026-15059 CVE-2026-15060 CVE-2026-16742

An attacker can exploit multiple vulnerabilities in systemd to escalate privileges, manipulate or disclose data, bypass security measures, trigger a Denial of Service condition, or execute arbitrary code with root privileges.

CSIRTS triage

vendor: systemd product: systemd Privilege escalation Information disclosure Authentication bypass Denial of service Remote code execution

What: Multiple vulnerabilities allow privilege escalation, data manipulation/disclosure, security bypass, denial of service, and arbitrary code execution as root.
Who is affected: All systemd deployments; local attackers can achieve root-level compromise.
Urgency: High despite medium rating; root rce and privilege escalation mean all affected systems are critical.
Action: Apply security patches for systemd immediately across all systems.
