Kerentanan Out-of-bounds Read pada ibm power system s922 (9009-22g) firmware, ibm power system h922 (9223-22s) firmware +8 lainnya. Skor CVSS 3.1 7.3 (High) menurut us.ibm.com.

Deskripsi (NVD)

IBM Power Systems Firmware FW950.00 through FW950.H2, OP940.00 through OP940.a1 (Power9), and OP940.00 - OP940.81 (Power HMC) is affected by a vulnerability in host firmware NVRAM parsing. An attacker with root access to a guest partition on an OpenPOWER system can write a specially crafted NVRAM image, causing the host firmware boot stage to crash with possible memory corruption. This condition persists until operator intervention — clearing NVRAM via the service processor — to restore normal operation. This vulnerability only affects OpenPOWER systems; systems running PowerVM are not affected. Successful exploitation results in an integrity and availability impact to the managed system.
