Fixed a long time ago by commit 8dc9384b7d75 ("xfs: reduce kvmalloc
overhead for CIL shadow buffers").
Please only report fuzzer bugs if they can be reproduced on a
current top of tree kernel release. If they can't, then we've
already fixed it. In that case, you can easily do the work (e.g. a
bisect) to find which commit fixed it yourself....
