The get_name function in net/tipc/socket.c in the Linux kernel before 2.6.37-rc2 does not initialize a certain structure, which allows local users to obtain potentially sensitive information from kernel stack memory by reading a copy of this structure.
Weakness
The product does not initialize a critical resource.
