CVE-2009-1758 is a vulnerability of currently unknown severity. The hypervisor_callback function in Xen, possibly before 3.4.0, as applied to the Linux kernel 2.6.30-rc4, 2.6.18, and probably other versions allows guest user applications to cause a denial of service (kernel oops) of the guest OS by triggering a segmentation fault in "certain address ranges.". EPSS estimates a 2.16% chance of exploitation in the next 30 days.
