OpenBMC IPMI Privilege Escalation via Retargeted RAKP 1

CVSS 3.1 8.8 HIGHCheck source for fixed versionsKEV status unknown

Original advisory

cve-program · CVE-2026-16140

Published

OpenBMC's IPMI implementation, phosphor-net-ipmid, is vulnerable to a logic flaw where the authorization context of an existing session can be replaced with a target account while still maintaining the original integrity and encryption keys. Several downstream vendors implement phosphor-net-ipmid as their IPMI stack, such as NVIDIA and H3C. This issue effectively allows for privilege escalation without re-authentication.
