Bugzilla:
698057: CVE-2011-1598 CVE-2011-1748 kernel: missing check in can/bcm and can/raw socket releases

The MITRE CVE dictionary describes this issue as:

The raw_release function in net/can/raw.c in the Linux kernel before 2.6.39-rc6 does not properly validate a socket data structure, which allows local users to cause a denial of service (NULL pointer dereference) or possibly have unspecified other impact via a crafted release operation.

Statement

The Linux kernel as shipped with Red Hat Enterprise Linux 3, 4 and 5 did not
include support for the CAN protocol, and therefore are not affected by this
issue. This has been addressed in Red Hat Enterprise Linux 6 and Red Hat Enterprise MRG via https://rhn.redhat.com/errata/RHSA-2011-0836.html, and https://rhn.redhat.com/errata/RHSA-2011-1253.html.
