A vulnerability has been identified in Xen, which could be exploited by local attackers to cause a denial of service or gain elevated privileges. This issue is caused by a buffer overflow error when processing specially crafted arguments passed to the "flask_op" hypercall of the "XSM:Flask" module , which could allow malicious domain users (domU) to crash an affected system or execute arbitrary code with elevated privileges.
