CVE-2026-44932

Code execution via unescaped DHCP lease strings

Published Jun 16, 2026 · Updated Jun 16, 2026

OS command injection in SUSE wicked before 0.6.79 allows remote attackers controlling a DHCP server to execute code on the client. The leaseinfo dump writes DHCP reply strings inside single-quoted key-value lines without escaping embedded single quotes, allowing consumers to interpret injected shell syntax. Exploitation requires a malicious DHCP server reachable by the client and a downstream script that processes the generated /run/wicked/leaseinfo.* file.
