## Description

net/packet/af\_packet.c in the Linux kernel before 2.6.37-rc2 does not
properly initialize certain structure members, which allows local users to
obtain potentially sensitive information from kernel stack memory by
leveraging the CAP\_NET\_RAW capability to read copies of the applicable
structures.

### From the Ubuntu Security Team

Vasiliy Kulikov discovered that the Linux kernel sockets implementation did
not properly initialize certain structures. A local attacker could exploit
this to read kernel stack memory, leading to a loss of privacy.
