Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue is related to the use of nfs folio length without proper locking and checks, which can lead to kernel crashes due to truncations. This occurs when running xfstests generic/065 with all nfs trace points enabled. The solution involves passing explicit offset and length to trace events, following the model of XFS trace points, to provide more accurate values.
