CVE-2026-40226 [MEDIUM] systemd vulnerabilities
Title: systemd vulnerabilities
Summary: Several security issues were fixed in systemd.

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.

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.
