In the Linux kernel, the following vulnerability has been resolved:
tipc: guard against string buffer overrun
Smatch reports that copying media_name and if_name to name_parts may
overwrite the destination.
.../bearer.c:166 bearer_name_validate() error: strcpy() 'media_name' too large for 'name_parts->media_name' (32 vs 16)
.../bearer.c:167 bearer_name_validate() error: strcpy() 'if_name' too large for 'name_parts->if_name' (1010102 vs 16)
This does seem to be the case so guard against this possibility by using
strscpy() and failing if truncation occurs.
Introduced by commit b97bf3fd8f6a ("[TIPC] Initial merge")
Compile tested only.
