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.

The CVE record on cve.org NVD's entry
The CVE record is authoritative. Products marked “from the name” were identified from the CNA's free-text names, not a CPE, and are matched less certainly. This product uses the NVD API but is not endorsed or certified by the NVD.
