About this tag
The NFS tag on WindowsForum.com covers security vulnerabilities and performance discussions related to the Network File System protocol. Threads detail critical CVEs in Das U-Boot's NFS client code (CVE-2019-14197, CVE-2019-14198, CVE-2019-14200, CVE-2019-14203) that enable remote code execution during network boot, as well as Linux kernel NFS bugs (CVE-2025-38400, CVE-2025-68349, CVE-2025-40273) causing crashes, denial of service, or list corruption. A comparison thread explains why NFS often outperforms SMB for Linux/Unix workloads and how to use both protocols. Topics include buffer overflows, memory safety, kernel stability, and practical file-sharing advice.

    CVE-2019-14200: U-Boot NFS Buffer Overflow Risk and Mitigation

    A critical stack-based buffer overflow in Das U-Boot’s NFS reply parsing — tracked as CVE-2019-14200 — exposes a long-standing attack surface for devices that use network boot or NFS-mounted filesystems during early boot, allowing malformed NFS replies to corrupt memory and, in the worst case...

    CVE-2019-14198 Unbounded memcpy in U-Boot NFS reply enables remote code execution

    An unbounded memcpy in U-Boot’s NFS reply handler left a wide swath of embedded and development hardware exposed to remote memory corruption and — in many realistic configurations — remote code execution during network boot operations, a defect formally tracked as CVE-2019-14198. (nvd.nist.gov)...

    CVE-2019-14203: U-Boot NFS Buffer Overflow Risk During Boot

    Das U‑Boot ships with a dangerous surprise in its NFS reply handling: a stack‑based buffer overflow in the nfs_mount_reply helper (tracked as CVE‑2019‑14203) that affects U‑Boot releases up through and including 2019.07 and — in certain configurations — permits remote attackers controlling a...

    CVE-2019-14197: U Boot NFS Read Out of Bounds Fix and Mitigations

    Das U‑Boot contained a network‑exposed memory‑safety flaw — CVE‑2019‑14197 — that allowed an attacker controlling or impersonating an NFS server to trigger an out‑of‑bounds read inside the NFS reply parser (nfs_read_reply), with real potential to leak sensitive memory and, in certain...

    Linux Kernel NFS Proc Cleanup Bug Fix CVE-2025-38400

    A subtle error-handling bug in the Linux kernel's NFS code — tracked as CVE-2025-38400 — has been fixed: when the initialization routine nfs_fs_proc_net_init fails, the kernel could leave behind a /proc/net/rpc/nfs entry and later log warnings or leak state during namespace teardown, a problem...

    CVE-2025-68349: Linux NFSv4/pNFS Crash and Local DoS Mitigation

    A recently assigned CVE, CVE-2025-68349, identifies a stability flaw in the Linux kernel’s NFSv4/pNFS client code where a missing flag clear can let the kernel attempt to reference a null layout during layoutcommit handling — a condition that causes a kernel crash and creates a local...

    CVE-2025-40273 Linux NFSd fix prevents copynotify list corruption

    The Linux kernel has a newly published security advisory — CVE-2025-40273 — describing a flaw in the NFS server (nfsd) state-management code: a copynotify stateid can remain referenced when its parent open state is freed, leading to list corruption and a kernel OOPS when laundromat later...

    NFS vs SMB: Why NFS Often Outperforms SMB and How to Use Both

    NFS still feels like the power-user option — awkward to configure, but when it’s right it can absolutely smoke SMB for many common Linux/Unix file‑sharing workloads. Background / Overview Local file sharing on home networks and small labs is dominated by two families of protocols: SMB (Server...

    Why Enabling Both NFS and SMB on Your NAS Enhances Compatibility and Performance

    When it comes to configuring network-attached storage (NAS) for home or small business use, the debate between Server Message Block (SMB) and Network File System (NFS) as file-sharing protocols often becomes a focal point. But what’s sometimes overlooked is the practical reality that using...
