Fixed In Version: qemu-kvm-ma-2.12.0-1.el7 Doc Type: Bug Fix
Doc Text:
Previously, system calls to the address_space_to_flatview function in some cases targeted functions that were not sufficiently synchronized by the read-copy-update (RCU) mechanism. This was a potential security risk. The affected system calls have been fixed, and they can no longer be used as a vector for malicious code.
