About this tag
CVE-2019-14194 is a high-severity vulnerability in U-Boot, the widely used open-source bootloader for embedded systems. The flaw resides in the NFS (Network File System) code, specifically in the handling of NFSv2 reply packets. An unbounded memcpy operation allows an attacker on the same network to trigger a buffer overflow, potentially leading to remote code execution. This affects U-Boot versions up to 2019.07. While the vulnerability has been patched, it serves as a critical reminder for embedded developers and firmware engineers that bootloaders are not immune to security flaws and require rigorous hardening, especially when used in development or diskless boot environments.

  1. CVE-2019-14194: Unbounded memcpy in U-Boot NFS leads to remote compromise

    An out-of-bounds memcpy in U-Boot’s NFS code left development and diskless systems open to remote compromise — a subtle, high‑impact bug tracked as CVE‑2019‑14194 that illustrates how a single failed length check in bootloader networking code can translate into full system compromise. The...
