In the Linux kernel, the following vulnerability has been resolved:
[ceph] parse_longname(): strrchr() expects NUL-terminated string
... and parselongname() is not guaranteed that. That's the reason why it uses kmemdupnul() to build the argument for kstrtou64(); the problem is, kstrtou64() is not the only thing that need it.
Just get a NUL-terminated copy of the entire thing and be done with that...
