CVE-2010-4565
The MITRE CVE dictionary describes this issue as:
The bcm_connect function in net/can/bcm.c (aka the Broadcast Manager) in the Controller Area Network (CAN) implementation in the Linux kernel 2.6.36 and earlier creates a publicly accessible file with a filename containing a kernel memory address, which allows local users to obtain potentially sensitive information about kernel memory use by listing this filename.

Statement
The Linux kernel as shipped with Red Hat Enterprise Linux 3, 4 and 5 did not
include CAN bus subsystem support, and therefore are not affected by this
issue. This has been addressed in Red Hat Enterprise MRG via https://rhn.redhat.com/errata/RHSA-2011-0330.html. A future kernel update in Red Hat Enterprise Linux 6 may address this flaw.
