CVE ID :CVE-2026-15816
Published : Aug. 7, 2026, 11:17 a.m. | 4 hours, 10 minutes ago
Description :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.
Severity: 7.5 | HIGH
