A stack-based buffer overflow vulnerability in Netatalk (CVE-2026-44048) allows a remote authenticated attacker to execute arbitrary code on systems running Netatalk versions 2.0.4 through 4.4.2. Netatalk is widely deployed on Linux and Unix servers to provide Apple Filing Protocol (AFP) file sharing with macOS clients. Organizations using Netatalk for mixed-OS file sharing environments face direct risk of system compromise and service disruption.
