CVE-2026-6893 not yet assigned priority: Debian including 1 source packages (dracut), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): open 5.
A flaw was found in dracut. A remote attacker on the adjacent network can exploit this vulnerability by providing specially crafted DHCP (Dynamic Host Configuration Protocol) options, such as a malicious hostname, to a system using dracut's legacy DHCP path. These options are improperly handled and written into temporary shell scripts without proper escaping, leading to command injection. This allows the attacker to achieve root code execution within the initramfs, potentially compromising the system's boot and network behavior.
