CVE-2014-3645

CVSS v2.0

2.1

Baixa

VetorAV:L/AC:L/Au:N/C:N/I:N/A:P
Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 3.12
Description The issue is related to the KVM subsystem in the Linux kernel, specifically in the arch/x86/kvm/vmx.c file. It does not have an exit handler for the INVEPT instruction, which allows guest OS users to cause a denial of service (guest OS crash) via a crafted application. A local unprivileged guest user could use this flaw to crash the guest.
Recommendations For Linux kernel versions prior to 3.12, update to version 3.12 or later to resolve the issue. As a temporary workaround, consider restricting access to the KVM subsystem to minimize the risk of exploitation.
