CVE-2010-0309

New! CVE Severity Now Using CVSS v3

The calculated severity for CVEs has been updated to use CVSS v3 by default. CVEs that do not have a CVSS v3 score will fall back CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Description

The pit_ioport_read function in the Programmable Interval Timer (PIT) emulation in i8254.c in KVM 83 does not properly use the pit_state data structure, which allows guest OS users to cause a denial of service (host OS crash or hang) by attempting to read the /dev/port file.
