CVE-2026-4932

IBM PowerVM Hypervisor FW1110.00 through FW1110.20, and FW1060.00 through FW1060.71 could allow an attacker with physical access to the Transparent Memory Encryption (TME) hardware to decrypt encrypted memory due to insufficient cryptographic entropy.

Does this matter?

Lower severity and a low EPSS score (0.08%). Track it; it rarely justifies an emergency change on its own.
