Thanks for the report.  However, this is not a bug.

Look at 'man 2 uname'.  On Linux, the uname.release version contains a
numeric string.  The uname.version field is not documented as to it's
contents, but POSIX merely requires that release and version together
identify the operating system kernel.  As confusing as it may be, this
behavior is a kernel choice, and coreutils uname(1) has no control over
it.  Coreutils is accurately reporting what the kernel told it.
