Impact
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 access controls over privileged system configuration operations on the FSP. An attacker with authenticated administrator-level access to the FSP can place the managed system into a non-production operational mode, allowing certain system components to be disabled. This condition persists across FSP resets and requires explicit operator intervention — clearing the affected configuration — to restore normal operation. Successful exploitation results in an availability impact to the managed system.
