This scheme is used to maintain invariants required for Xen's safety, e.g. PV guests may not have direct writeable access to pagetables; updates need auditing by Xen. Unfortunately, the logic for acquiring a type reference has a race condition, whereby a safely TLB flush is issued too early and creates a window where the guest can re-establish the read/write mapping before ... • https://packetstorm.news/files/id/167718 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
