CVE-2014-1642

CVE-2014-1642 affects Xen 4.2.x and 4.3.x when using device passthrough with large CPU counts. The IRQ setup frees memory that may still be in use, causing memory corruption and a hypervisor crash. Local guest administrators can trigger a denial of service, and, via the out-of-memory path, may ex...

Out-of-memory condition yielding memory corruption during IRQ setup

ISSUE DESCRIPTION When setting up the IRQ for a passed through physical device, a flaw in the error handling could result in a memory allocation being used after it is freed, and then freed a second time. This would typically result in memory corruption. IMPACT Malicious guest administrators can...
