An update for dracut is now available for openEuler-22.03-LTS-SP4 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2026-3301 Final 1.0 1.0 2026-08-07 Initial 2026-08-07 2026-08-07 openEuler SA Tool V1.0 2026-08-07 dracut security update An update for dracut is now available for openEuler-22.03-LTS-SP4 dracut contains tools to create bootable initramfses for the Linux kernel. Unlike previous implementations, dracut hard-codes as little as possible into the initramfs. dracut contains various modules which are driven by the event-based udev. Having root on MD, DM, LVM2, LUKS is supported as well as NFS, iSCSI, NBD, FCoE with the dracut-network package. Security Fix(es): A flaw was found in dracut. A remote attacker on the adjacent network can exploit this vulnerability by providing specially crafted DHCP options, such as a malicious root-path, next-server, or bootfile name, to a system using dracut's NetworkManager-based initrd network module. These options are improperly handled and written into a temporary shell script without proper escaping, leading to command injection. This allows the attacker to achieve root code execution within the initramfs during system boot.(CVE-2026-16445) An update for dracut is now available for openEuler-22.03-LTS-SP4. openEuler Security has rated this update as having a security impact of high.
