This CVE record has been updated after NVD enrichment efforts were completed. Enrichment data supplied by the NVD may require amendment due to these changes.
Description
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.
