AI Powered Q&A
Can you explain this vulnerability to me?
CVE-2025-36035 is a vulnerability in the IBM PowerVM hypervisor used in IBM Power Systems. It allows a local privileged user to cause a denial of service (DoS) by issuing a specially crafted IBM i hypervisor call. This can either crash the system or cause limited disclosure of memory contents by improperly making some system memory available. The issue is related to allocation of resources without proper limits or throttling. [1]
How can this vulnerability impact me? :
This vulnerability can impact you by allowing a local privileged user to cause a denial of service, which can crash the system or consume excessive memory resources, potentially disrupting availability. It can also lead to limited disclosure of memory contents, which may expose sensitive information. The impact on confidentiality is low, integrity is not affected, but availability impact is high. [1]
What immediate steps should I take to mitigate this vulnerability?
To mitigate CVE-2025-36035, you should apply the recommended firmware updates for your affected IBM Power Systems. For Power 9 systems, install firmware updates 950.E1 (950_182) or 950.F0 (950_192) or newer. For Power 10 systems, install firmware updates FW1050.51 (1050_095), FW1050.60 (1050_090), FW1060.41 (1060_120), or newer. No other workarounds or mitigations are available. Additionally, subscribe to IBM security notifications for future updates. [1]
