CVE-2014-9065

CVE-2014-9065 affects Xen 4.4.x and earlier. The issue lies in common/spinlock.c where read/write lock handling is incomplete, enabling local x86 guest users to cause a denial of service (write denial or NMI watchdog timeout and host crash) by issuing a large number of read requests. Connected do...

p2m lock starvation

ISSUE DESCRIPTION The current read/write lock implementation is read-biased, which allows a consistent stream of readers to starve writers indefinitely. There are certain rwlocks where guests are capable of applying arbitrary read pressure. IMPACT A malicious guest administrator can deny service ...
