CVE-2013-3495
CVSS v2.0
4.7
Média
| Vetor | AV:L/AC:M/Au:N/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
Xen versions 3.3.x through 4.3.x
Description
The issue allows local guests to cause a denial of service, resulting in a kernel panic. This is achieved by sending a malformed Message Signaled Interrupt (MSI) from a PCI device capable of bus mastering, which triggers a System Error Reporting (SERR) Non-Maskable Interrupt (NMI).
Recommendations
For Xen versions 3.3.x through 4.3.x, consider disabling the Interrupt Remapping engine as a temporary workaround until a patch is available. Restrict access to PCI devices that are bus mastering capable to minimize the risk of exploitation.
