CVE-2018-16871 is a critical null pointer dereference vulnerability affecting the Linux kernel's NFS implementation (versions 3.x and 4.x up to 4.20), impacting products like Linux, NetApp, and Red Hat. An unauthenticated attacker can trigger a denial-of-service by mounting an exported NFS filesystem and sending an invalid NFS sequence, causing the server to panic and lose outstanding disk writes. With a CVSS score of 7.5 (High), this vulnerability is remotely exploitable with low attack complexity, though there is no known active exploitation, public exploit code, or significant community discussion.
