Detailsinfo

A vulnerability was found in IBM PowerVM Hypervisor up to FW1060.81/FW1110.31/FW1120.01. It has been classified as very critical. Affected is an unknown functionality of the component Boot Process. The manipulation with an unknown input leads to a code injection vulnerability. CWE is classifying the issue as CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

IBM Power Systems Firmware FW1120.00 through FW1120.01, FW1110.00 through FW1110.31, and FW1060.00 through FW1060.81 is affected by a vulnerability in the host firmware boot process image validation path. An attacker with service access to the service processor can supply a maliciously crafted code update image, allowing arbitrary code to be executed on the host system. Successful exploitation could result in a confidentiality, integrity, and availability impact to the affected host system.

The advisory is shared for download at ibm.com. This vulnerability is traded as CVE-2026-96263 since 09/22/2026. The exploitability is told to be easy. The attack needs to be approached locally. Additional levels of successful authentication are needed for exploitation. There are neither technical details nor an exploit publicly available. The current price for an exploit might be approx. USD $5k-$25k (estimation calculated on 10/12/2026). The MITRE ATT&CK project declares the attack technique as T1059.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
