{"id":"OESA-2026-3501","summary":"dracut security update","details":"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.\r\n\r\nSecurity Fix(es):\n\nA 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)","modified":"2026-08-30T04:31:36.984488250Z","published":"2026-08-30T04:14:14Z","upstream":["CVE-2026-15816"],"database_specific":{"severity":"High"},"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-3501"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-15816"}],"affected":[{"package":{"name":"dracut","ecosystem":"openEuler:22.03-LTS-SP4","purl":"pkg:rpm/openEuler/dracut&distro=openEuler-22.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"055-20.oe2203sp4"}]}],"ecosystem_specific":{"aarch64":["dracut-055-20.oe2203sp4.aarch64.rpm","dracut-caps-055-20.oe2203sp4.aarch64.rpm","dracut-config-generic-055-20.oe2203sp4.aarch64.rpm","dracut-config-rescue-055-20.oe2203sp4.aarch64.rpm","dracut-debuginfo-055-20.oe2203sp4.aarch64.rpm","dracut-debugsource-055-20.oe2203sp4.aarch64.rpm","dracut-live-055-20.oe2203sp4.aarch64.rpm","dracut-network-055-20.oe2203sp4.aarch64.rpm","dracut-squash-055-20.oe2203sp4.aarch64.rpm","dracut-tools-055-20.oe2203sp4.aarch64.rpm"],"src":["dracut-055-20.oe2203sp4.src.rpm"],"x86_64":["dracut-055-20.oe2203sp4.x86_64.rpm","dracut-caps-055-20.oe2203sp4.x86_64.rpm","dracut-config-generic-055-20.oe2203sp4.x86_64.rpm","dracut-config-rescue-055-20.oe2203sp4.x86_64.rpm","dracut-debuginfo-055-20.oe2203sp4.x86_64.rpm","dracut-debugsource-055-20.oe2203sp4.x86_64.rpm","dracut-live-055-20.oe2203sp4.x86_64.rpm","dracut-network-055-20.oe2203sp4.x86_64.rpm","dracut-squash-055-20.oe2203sp4.x86_64.rpm","dracut-tools-055-20.oe2203sp4.x86_64.rpm"]},"database_specific":{"source":"https://repo.openeuler.org/security/data/osv/OESA-2026-3501.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
