Upstream information

CVE-2012-2373 at MITRE

Description

The Linux kernel before 3.4.5 on the x86 platform, when Physical Address Extension (PAE) is enabled, does not properly use the Page Middle Directory (PMD), which allows local users to cause a denial of service (panic) via a crafted application that triggers a race condition.

NVD CVSS v2 Base Score: 4.0 (AV:L/AC:H/Au:N/C:N/I:N/A:C)

Novell/SUSE information

Note from the SUSE Security Team

This affects only kernels with transparent huge pages support, so SLES 11 SP1, SLES 10 and earlier are not affected. SLES 11 SP2 and openSUSE 12.1 received fixes already.

Novell Bugzilla entry: 653148, 762991
