CVE-2026-16140 (GCVE-0-2026-16140)

Title
OpenBMC IPMI Privilege Escalation via Retargeted RAKP 1
Summary
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.
