dracut-049-246.git20260728.el8_10

The dracut packages contain an event-driven initial RAM file system (initramfs) generator infrastructure based on the udev device manager. The virtual file system, initramfs, is loaded together with the kernel at boot time and initializes the system, so it can read and boot from the root partition.

Security Fix(es):

* dracut: dracut: root code execution via unescaped error message written to sourced emergency hook script in die() (CVE-2026-15816)

CVE-2026-15816
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.
