649695: CVE-2010-3874 kernel: CAN minor heap overflow

The MITRE CVE dictionary describes this issue as:

Heap-based buffer overflow in the bcm_connect function in net/can/bcm.c (aka the Broadcast Manager) in the Controller Area Network (CAN) implementation in the Linux kernel before on 64-bit platforms might allow local users to cause a denial of service (memory corruption) via a connect operation.

Find out more about CVE-2010-3874 from the MITRE CVE dictionary dictionary and NIST NVD.


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. Future kernel updates in Red Hat Enterprise Linux 6 and Red Hat Enterprise MRG may address this flaw.
