| Vetor | AV:A/AC:L/Au:N/C:C/I:C/A:C |
Name of the Vulnerable Software and Affected Versions
Xen versions 4.1 through 4.4.x
Description
The issue is related to the
hvm msr read intercept function in the arch/x86/hvm/hvm.c file, which improperly handles the MSR range for x2APIC emulation. This allows local HVM guests to cause a denial of service, resulting in a host crash, or to read data from the hypervisor or other guests.Recommendations
For Xen versions 4.1 through 4.4.x, consider restricting access to the
hvm msr read intercept function as a temporary workaround until a patch is available.Correção
