Buffer overflow

/ˈbʌfər ˈoʊvərfloʊ/ noun

A security vulnerability that occurs when a program writes more data to a buffer than it can hold, potentially overwriting adjacent memory and allowing malicious code execution.

Combines 'buffer' (1950s computing term for temporary storage) with 'overflow' from mathematics. The security implications became notorious in the 1988 Morris Worm, making it a cornerstone of cybersecurity education.
