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.
