## Overview

In the Linux kernel, the following vulnerability has been resolved:

tipc: Dont send random pad bytes in RESET/ACTIVATE messages

The interface name is passed in a fixed length (TIPC_MAX_IF_NAME) buffer.
Replace the strcpy(data, l->if_name) with memcpy() so that the
pad bytes are actually written (l->if_name[] is zero padded)
rather than sending random bytes from the skb to the remote system.

Replace two other strcpy() with strscpy().

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
