5.7
Média
| Vetor | AV:A/AC:M/Au:N/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
Xen versions 3.3 through 4.3
Description
The issue allows local HVM guests with access to memory mapped I/O regions to cause a denial of service. This can result in CPU consumption and possibly hypervisor or guest kernel panic via a crafted GFN range. The
vmx set uc mode function is involved when disabling caches.Recommendations
For Xen versions 3.3 through 4.3, consider disabling the
vmx set uc mode function as a temporary workaround until a patch is available. Restrict access to memory mapped I/O regions to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.DoS
