Comment 5 Jan Lieskovsky 2009-10-20 08:44:42 UTC
MITRE's CVE-2009-3228 record:

The tc_fill_tclass function in net/sched/sch_api.c in the tc subsystem
in the Linux kernel 2.4.x before and 2.6.x before 2.6.31-rc9
does not initialize certain (1) tcm__pad1 and (2) tcm__pad2 structure
members, which might allow local users to obtain sensitive information
from kernel memory via unspecified vectors.
