In the Linux kernel, the following vulnerability has been resolved:
NFSv4: Fix a NULL pointer dereference in pnfs_mark_matching_lsegs_return()
Commit de144ff4234f changes _pnfs_return_layout() to call
pnfs_mark_matching_lsegs_return() passing NULL as the struct
pnfs_layout_range argument. Unfortunately,
pnfs_mark_matching_lsegs_return() doesn't check if we have a value here
before dereferencing it, causing an oops.
I'm able to hit this crash consistently when running connectathon basic
tests on NFS v4.1/v4.2 against Ontap.
