AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N

Name of the Vulnerable Software and Affected Versions Xen versions 4.5 through 4.9

Description The issue arises when Xen incorrectly clears the status bits too early, informing the guest that a grant is no longer in use. This can lead to a guest prematurely reusing a granted frame that still contains sensitive information, as the domain on the far end of the grant is still using it.

Recommendations For Xen versions 4.5 through 4.9, at the moment, there is no information about a newer version that contains a fix for this vulnerability.
