Description Petr Matousek 2010-11-04 12:10:33 UTC

Structure sockaddr_tipc is copied to userland with padding bytes after "id" field in union field "name" unitialized.  It leads to leaking of contents of kernel stack memory.  We have to initialize them to zero.

Comment 2 Petr Matousek 2010-11-04 18:49:09 UTC 
Statement:

This issue did not affect the version of Linux kernel as shipped with Red Hat
Enterprise Linux 3, 4 and Red Hat Enterprise MRG as they did not include
support for Transparent Inter-Process Communication Protocol (TIPC). A future
kernel update in Red Hat Enterprise Linux 5 may address this flaw.
