Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 2.6.39-rc6

Description The issue is related to the raw release function in net/can/raw.c, which does not properly validate a socket data structure. This can be exploited by local users to cause a denial of service, resulting in a NULL pointer dereference, or possibly have other unspecified impacts via a crafted release operation.

Recommendations For versions prior to 2.6.39-rc6, update to version 2.6.39-rc6 or later to resolve the issue.
