CVE-2010-0730

Status: ModifiedLow (2.6)—

The MMIO instruction decoder in the Xen hypervisor in the Linux kernel 2.6.18 in Red Hat Enterprise Linux (RHEL) 5 allows guest OS users to cause a denial of service (32-bit guest OS crash) via vectors that trigger an unspecified instruction emulation.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
