7.3 highCVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:L/A:HCVE-2026-18871
High (7.3) in ibm. EPSS 0.1% chance of exploitation in the next 30 days.
IBM PowerVM Hypervisor FW1120.00, FW1110.00 through FW1110.30, and FW1060.00 through FW1060.80 is affected by a vulnerability in host firmware configuration parsing. An attacker with authenticated service-level access to the service processor can write specially crafted configuration data, causing the host firmware boot stack to crash with possible memory corruption during system initialisation, resulting in an integrity and availability impact to the managed system.
