HCE2-SA-2025-0221 Important HCE 2.0 Security Fix(es): cloud-init through 25.1.2 includes the systemd socket unit cloud-init-hotplugd.socket with default SocketMode that grants 0666 permissions, making it world-writable. This is used for the "/run/cloud-init/hook-hotplug-cmd" FIFO. An unprivileged user could trigger hotplug-hook commands. (CVE-2024-11584) When a non-x86 platform is detected, cloud-init grants root access to a hardcoded url with a local IP address. To prevent this, cloud-init default configurations disable platform enumeration. (CVE-2024-6174) HCE 2.0 cloud-init-21.4-2.r15.hce2.noarch.rpm cloud-init-help-21.4-2.r15.hce2.noarch.rpm
