CVE-2025-21895 is a medium-severity vulnerability in the Linux kernel's perf subsystem related to unordered perf_event_pmu_context lists. The issue causes warnings triggered by mismatched ordering of PMU context lists between parent and child processes, which can lead to instability or crashes. The problem arises because the order of PMU contexts in the parent and child differ due to how events are added and inherited. A fix was implemented to insert the PMU context in the correct order to resolve this warning.
