Amazon Linux 2023 Security Advisory: ALAS2023-2026-2085
Advisory Released Date: 2026-08-31
Advisory Updated Date: 2026-08-31
Severity:
Important
Issue Overview:
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. (CVE-2026-15816)
Affected Packages:
dracut
Issue Correction:
Run dnf update dracut --releasever 2023.12.20260831 or dnf update --advisory ALAS2023-2026-2085 --releasever 2023.12.20260831 to update your system.
