IBM Powervm Hypervisor

IBM Power FW security bypass

IBM PowerVM Hypervisor FW860, FW940, and FW950 could allow an attacker that gains service access to the FSP can read and write arbitrary host system memory through a series of carefully crafted service procedures. IBM X-Force ID: 210018.

IBM PowerVM gain access

IBM PowerVM Hypervisor FW1010 could allow a privileged user to gain access to another VM due to assigning duplicate WWPNs. IBM X-Force ID: 210162.

IBM PowerVM Hypervisor FW860, FW940, FW950, and FW1010, through a specific sequence of VM management operations could lead to a violation of the isolation between peer VMs. IBM X-Force ID: 210019.

IBM PowerVM Hypervisor denial of service

An attacker that gains service access to the FSP (POWER9 only) or gains admin authority to a partition can compromise partition firmware.

IBM PowerVM Hypervisor information disclosure

IBM PowerVM Hypervisor FW940, FW950, and FW1010 could allow an authenticated user to cause the system to crash using a specially crafted IBMi Hypervisor call. IBM X-Force ID: 210894.

IBM PowerVM Hypervisor denial of service

IBM PowerVM Hypervisor FW860, FW930, FW940, and FW950 could allow a local user to create a specially crafted sequence of hypervisor calls from a partition that could crash the system. IBM X-Force ID: 203557.

IBM PowerVM Hypervisor data manipulation

The PowerVM Logical Partition Mobility(LPM) (PowerVM Hypervisor FW920, FW930, FW940, and FW950) encryption key exchange protocol can be compromised. If an attacker has the ability to capture encrypted LPM network traffic and is able to gain service access to the FSP they can use this information to perform a series of PowerVM service procedures to decrypt the captured migration traffic IBM X-Force ID: 198232
