Details
A vulnerability was found in IBM PowerVM Hypervisor up to FW950.H2/FW1060.80/FW1110.30/FW1120.00. It has been declared as very critical. Affected by this vulnerability is an unknown code of the component Network Boot. The manipulation with an unknown input leads to a input validation vulnerability. The CWE definition for the vulnerability is CWE-20. The product receives input or data, but it does
not validate or incorrectly validates that the input has the
properties that are required to process the data safely and
correctly. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:
IBM PowerVM Hypervisor FW1120.00, FW1110.00 through FW1110.30, FW1060.00 through FW1060.80, and FW950.00 through FW950.H2 Power Systems Firmware is affected by a vulnerability in partition firmware during network boot. An unauthenticated attacker with access to the same network as a partition performing a network boot can prevent that partition from completing its boot sequence. On partitions where OS secure boot is not enabled, which is the default configuration, the attacker can also substitute the boot image, compromising everything subsequently loaded by that partition. Other partitions and the managed system are not affected. Only partitions actively performing a network boot are affected, resulting in a confidentiality, integrity, and availability impact.
The advisory is shared at ibm.com. This vulnerability is known as CVE-2026-17414 since 07/25/2026. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $5k-$25k at the moment (estimation calculated on 08/19/2026).
There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
