CVE-2021-38201 is a high-severity denial-of-service vulnerability affecting the Linux kernel (versions before 5.13.4) and NetApp products, stemming from an out-of-bounds memory access in the NFS 4.2 READ_PLUS operation. This flaw can be triggered remotely without authentication or user interaction, leading to system unavailability. While no active exploits, public exploit code, or significant community discussion have been observed, its high CVSS score of 7.5 indicates a significant risk.
