Hi, The following vulnerability was published for dracut. CVE-2026-15816[0]: | A flaw was found in dracut. The die() error-handling function writes | its message into a shell script under the initramfs emergency-hook | directory without properly shell-quoting it. When the message | contains data derived from the DHCP ROOT_PATH option, an attacker on | the adjacent network who controls a rogue DHCP server can inject a | command-substitution sequence that executes as root the next time | dracut sources its emergency hook scripts during standard boot- | failure handling. https://bugzilla.redhat.com/show_bug.cgi?id=2500889 If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
