CVE-2012-1179

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 3.3.1

Description The issue allows guest OS users to cause a denial of service (host OS crash) by leveraging administrative access to the guest OS, related to the pmd none or clear bad function and page faults for huge pages. A privileged user in the KVM guest can use this flaw to crash the host. An unprivileged local user could use this flaw to crash the system.

Recommendations For versions prior to 3.3.1, update to version 3.3.1 or later to resolve the issue. As a temporary workaround, consider restricting administrative access to the guest OS to minimize the risk of exploitation.
