Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 2.6.31-rc7

Description: The issue is related to the llc ui getname function in the Linux kernel, which does not properly initialize a certain data structure. This allows local users to read the contents of some kernel memory locations by calling getsockname on an AF LLC socket.

Recommendations: For Linux kernel versions prior to 2.6.31-rc7, consider upgrading to a newer version to resolve the issue. As a temporary workaround, restrict access to AF LLC sockets to minimize the risk of exploitation.
