Virtual TPM disclosure via service procedures
Published Feb 2, 2026 · Updated Feb 2, 2026
Information disclosure in IBM PowerVM Hypervisor allows local users with administration privileges to read sensitive Virtual TPM data. A series of PowerVM service procedures exposes the data, but IBM has not published the affected procedure names or the operation that mishandles the Virtual TPM contents. Exploitation requires local system-administrator access and affects confidentiality only, with no reported ability to modify the data or interrupt the hypervisor.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=FW1060.00 <=FW1060.51
- Affected versionversion=FW1110.00 <=FW1110.03
- Affected versionversion=FW950.00 <=FW950.F0
