Description
IBM PowerVM Hypervisor FW1120.00 through FW1120.01, FW1110.00 through FW1110.31, FW1060.00 through FW1060.81, and FW950.00 through FW950.H3 is affected by a vulnerability in the partition firmware runtime boot configuration. An attacker with root access to a partition can maliciously alter partition nvram, causing the partition to fail to boot. This condition persists until operator intervention — deleting and recreating the partition configuration — to restore normal operation. Successful exploitation results in an integrity and availability impact.
