CVE-2026-17100
HighCVSS 8.2Summary
Power Systems Firmware is affected by a vulnerability in the service processor mailbox interface. An attacker with authenticated service-level access to the BMC/FSP can exploit this to execute arbitrary code in the host firmware runtime, giving full control over the managed system.
Risk Assessment
Full compromise of the managed system, leading to confidentiality, integrity, and availability impact.
Recommendation
Apply firmware updates and restrict service-level access to BMC/FSP.
