Summary

A vulnerability in libnfs up to version 6.0.2 before commit 935b8db causes an integer underflow in the xid field in the READ_IOVEC function in lib/socket.c. The issue occurs when connecting to a crafted NFS server, where the expected PDU size exceeds the absolute PDU size from the xid/record-marker.
