Base vector

AV:L/AC:M/Au:N/C:P/I:N/A:N

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 3.8.4

Description The issue allows local users to obtain sensitive information from kernel stack memory. This is due to the rtnl fill ifinfo function in net/core/rtnetlink.c not initializing a certain structure member, which can be exploited via a crafted application.

Recommendations For Linux kernel versions prior to 3.8.4, update to version 3.8.4 or later to resolve the issue. As a temporary workaround, consider restricting access to the rtnl fill ifinfo function until a patch is available.
