Detailsinfo

A vulnerability, which was classified as critical, has been found in IBM PowerVM Hypervisor up to FW950.H2/FW1060.80/FW1110.30/FW1120.00. This issue affects an unknown code. The manipulation with an unknown input leads to a resource consumption vulnerability. Using CWE to declare the problem leads to CWE-400. The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources. Impacted is 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 is affected by a vulnerability in partition firmware during network boot. An unauthenticated attacker with access to the same network as a partition undergoing iSCSI SAN network boot can prevent that partition from completing its boot sequence. Other partitions and the managed system are not affected. Only partitions actively performing an iSCSI SAN network boot are affected, resulting in an availability impact.

It is possible to read the advisory at ibm.com. The identification of this vulnerability is CVE-2026-17028 since 07/24/2026. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. The technical details are unknown and an exploit is not publicly available.
