Power System update in Buffer Copy

IBM PowerVM Hypervisor FW1110.00 through FW1110.20, FW1060.00 through FW1060.71, and FW950.00 through FW950.H1 A carefully crafted OS hypervisor call can cause the PowerVM hypervisor to crash or compromise OS memory integrity.

IBM PowerVM Hypervisor denial of service

IBM PowerVM Hypervisor FW950.00 through FW950.E0, FW1050.00 through FW1050.50, and FW1060.00 through FW1060.40 could allow a local privileged user to cause a denial of service by issuing a specially crafted IBM i hypervisor call that would disclose memory contents or consume excessive memory resources.

IBM Flexible Service Processor hard coded credentials

IBM Flexible Service Processor (FSP) FW860.00 through FW860.B3, FW950.00 through FW950.C0, FW1030.00 through FW1030.61, FW1050.00 through FW1050.21, and FW1060.00 through FW1060.10 has static credentials which may allow network users to gain service privileges to the FSP.

IBM PowerVM Hypervisor information disclosure

IBM PowerVM Platform KeyStore (IBM PowerVM Hypervisor FW950.00 through FW950.90, FW1030.00 through FW1030.60, FW1050.00 through FW1050.20, and FW1060.00 through FW1060.10 functionality can be compromised if an attacker gains service access to the HMC. An attacker that gains service access to the HMC can locate and through a series of service procedures decrypt data contained in the Platform KeyStore.

IBM PowerVM gain access

An internally discovered vulnerability in PowerVM on IBM Power9 and Power10 systems could allow an attacker with privileged user access to a logical partition to perform an undetected violation of the isolation between logical partitions which could lead to data leakage or the execution of arbitrary code in other logical partitions on the same physical server. IBM X-Force ID: 252706.

The IBM Power 9 OP910, OP920, and FW910 boot firmware's bootloader is responsible for loading and validating the initial boot firmware image that drives the rest of the system's hardware initialization. The bootloader firmware contains a buffer overflow vulnerability such that, if an attacker were able to replace the initial boot firmware image with a very carefully crafted and sufficiently large, malicious replacement, it could cause the bootloader, during the load of that image, to overwrite its own instruction memory and circumvent secure boot protections, install trojans, etc. IBM X-Force ID: 154345.
