Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to a NULL pointer dereference in the
pnfs mark matching lsegs return() function. This occurs when the pnfs return layout() function calls pnfs mark matching lsegs return() with a NULL struct pnfs layout range argument, which is then dereferenced, causing a crash. The crash can be consistently reproduced when running connectathon basic tests on NFS v4.1/v4.2 against Ontap.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
