Medium

Base vector

AV:L/AC:M/Au:N/C:C/I:C/A:C

Name of the Vulnerable Software and Affected Versions Xen (affected versions not specified)

Description The issue is related to a race condition in the acquisition of type references in Xen. This condition allows a window where a guest can re-establish a read/write mapping before writeability is prohibited, potentially leading to the execution of arbitrary code. The type reference count scheme is used to maintain safety invariants, such as preventing PV guests from having direct writeable access to pagetables, which require auditing by Xen.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
