Detailsinfo

A vulnerability, which was classified as critical, was found in dracut (the affected version unknown). Affected is an unknown part. The manipulation with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is available at access.redhat.com. This vulnerability is traded as CVE-2026-6893 since 04/23/2026. The exploitability is told to be easy. The attack needs to be done within the local network. The exploitation doesn't require any form of authentication. The technical details are unknown and an exploit is not available.
