systemd vulnerabilities
Details
It was discovered that systemd-nspawn incorrectly handled certain optional configuration files. A local attacker could possibly use this issue to escape to the host system and execute arbitrary code. (CVE-2026-40226)
It was discovered that systemd-resolved incorrectly validated DNSSEC records for signed domains. An attacker could possibly use this issue to manipulate DNS records. This issue only affected Ubuntu 22.04 LTS. (CVE-2023-7008)
