Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

CVE-2025-58145

High
7.5/10

Summary

There is an issue related to the mapping of pages belonging to other domains: The P2M lock isn't held until a page reference was actually obtained (or the attempt to do so has failed). Otherwise the page can not only change type, but even ownership in between, thus allowing domain boundaries to be violated. This issue affects versions from 4.12.x prior to 4.21.0-rc1.

CWE-362 - Race Condition

A race condition occurs in a shared memory program when two threads/processes access the same shared memory data, and at least one thread executes a write operation. This vulnerability manipulates the time to check vs. time to use (TOC/TOU) gap between the threads in the critical section to cause disorientation in the shared data. The impact can vary from compromising the confidentiality of the system to causing the system to crash or to execute arbitrary code.
