CVE-2010-3881
Published: 23 December 2010
arch/x86/kvm/x86.c in the Linux kernel before 2.6.36.2 does not initialize certain structure members, which allows local users to obtain potentially sensitive information from kernel stack memory via read operations on the /dev/kvm device.
From the Ubuntu Security Team
Vasiliy Kulikov discovered that kvm did not correctly clear memory. A local attacker could exploit this to read portions of the kernel stack, leading to a loss of privacy.
Notes
| Author | Note |
|---|---|
| smb | Releases before Lucid do not contain the IOCTL functions affected. For ti-omap, mvl-dove and ec2 the change of KVM should not matter at all. |
