CVE-2010-4565

Published: 29 December 2010

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.

From the Ubuntu security team

Dan Rosenburg discovered that the CAN subsystem leaked kernel addresses into the /proc filesystem. A local attacker could use this to increase the chances of a successful memory corruption exploit.
