The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. As an impact it is known to affect availability. CVE summarizes:

The bcm_release function in net/can/bcm.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.
