CVE-2010-3876

Published: 3 January 2011

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.
