CVE-2012-4537
Last modified
CVE-2012-4537 is a vulnerability of currently unknown severity. Xen 3.4 through 4.2, and possibly earlier versions, does not properly synchronize the p2m and m2p tables when the set_p2m_entry function fails, which allows local HVM guest OS administrators to cause a denial of service (memory consumption and assertion failure), aka "Memory mapping failure DoS vulnerability.". EPSS estimates a 0.43% chance of exploitation in the next 30 days.
