Vulnerability from csaf_redhat - Published: 2011-01-13 10:59 - Updated: 2025-11-21 17:37Summary
Red Hat Security Advisory: kvm security and bug fix update
Severity
Low
Notes
Topic: Updated kvm packages that fix one security issue and several bugs are now
available for Red Hat Enterprise Linux 5.
The Red Hat Security Response Team has rated this update as having low
security impact. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available from the CVE link in
the References section.
Details: KVM (Kernel-based Virtual Machine) is a full virtualization solution for
Linux on AMD64 and Intel 64 systems. KVM is a Linux kernel module built for
the standard Red Hat Enterprise Linux kernel.
A data structure field in kvm_vcpu_ioctl_x86_get_vcpu_events() in QEMU-KVM
was not initialized properly before being copied to user-space. A
privileged host user with access to "/dev/kvm" could use this flaw to leak
kernel stack memory to user-space. (CVE-2010-4525)
Red Hat would like to thank Stephan Mueller of atsec information security
for reporting this issue.
These updated packages also fix several bugs. Documentation for these bug
fixes will be available shortly in the "kvm" section of the Red Hat
Enterprise Linux 5.6 Technical Notes, linked to in the References.
All KVM users should upgrade to these updated packages, which resolve this
issue as well as fixing the bugs noted in the Technical Notes. Note: The
procedure in the Solution section must be performed before this update will
take effect.

Linux kernel 2.6.33 and 2.6.34.y does not initialize the kvm_vcpu_events->interrupt.pad structure member, which allows local users to obtain potentially sensitive information from kernel stack memory via unspecified vectors.

Vendor Fix
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
http://kbase.redhat.com/faq/docs/DOC-11259
The following procedure must be performed before this update will take
effect:
1) Stop all KVM guest virtual machines.
2) Either reboot the hypervisor machine or, as the root user, remove (using
"modprobe -r [module]") and reload (using "modprobe [module]") all of the
following modules which are currently running (determined using "lsmod"):
kvm, ksm, kvm-intel or kvm-amd.
3) Restart the KVM guest virtual machines.
