CVE-2025-14558

Remote code execution via ND6 Router Advertisements

Published Mar 9, 2026 CVSS 3.1 · 7.2 High EPSS 6.7% KEV · Not listed
Description
The rtsol(8) and rtsold(8) programs do not validate the domain search list options provided in router advertisement messages; the option body is passed to resolvconf(8) unmodified.

resolvconf(8) is a shell script which does not validate its input. A lack of quoting meant that shell commands pass as input to resolvconf(8) may be executed.
