The exploitation is known to be easy. Local access is required to approach this attack. The successful exploitation requires a simple authentication. The technical details are unknown and an exploit is not available.

It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 1712 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 68148 (Oracle Linux 5 : kvm (ELSA-2010-0898)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Oracle Linux Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 155569 (Oracle Linux 5 Unbreakable Enterprise Kernel Security and Bug Fix Update (ELSA-2010-2011)).
