High CVSS 8.4

CVE-2026-16832

Ibm Power System E1080 \(9080-hex\) Firmware

IBM Power Systems Firmware FW1120.00, FW1110.00 through FW1110.30, FW1060.00 through FW1060.80, and FW950.00 through FW950.H2 is affected by a vulnerability in the FSP management network protocol. An attacker with authenticated HMC administrator access can execute arbitrary code on the service processor, giving full control over the managed system, resulting in a confidentiality, integrity, and availability impact.

What this means

Exposure
Exploitable from the adjacent network, with a privileged account and with no action from the victim.
Impact
An attacker can read sensitive data, modify or destroy data and take the service offline. The impact spreads beyond the vulnerable component into other parts of the system.
Weakness
A stack overflow overwrites the return address, which often leads to code execution.
Likelihood
Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
