A segmentation fault in JerryScript v3.0.0 occurs due to an assertion failure in the lexer when processing a malformed JavaScript code snippet. This can lead to a Denial of Service (DoS) as the application crashes when handling specific input, indicating a potential vulnerability in input validation.
