Name of the Vulnerable Software and Affected Versions Xen (affected versions not specified)

Description The issue is related to a buffer overflow in memory, which can allow an attacker to execute arbitrary code. Xen's safety logic does not account for CPU-induced cache non-coherency, leading to incorrect conclusions about page safety. This can occur when the CPU causes the content of the cache to differ from the content in main memory. The estimated number of potentially affected devices worldwide is not available. There is no information about real-world incidents where this issue was exploited.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
