Bugzilla:
664544: CVE-2010-4565 kernel: CAN info leak

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.

Find out more about CVE-2010-4565 from the MITRE CVE dictionary dictionary and NIST NVD.

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.
