What it is

⚠️ A sneaky buffer overflow is hiding in WebGL, ready to be triggered by crafty web content! Think of this like a crowded elevator where too many people push in at once—the system starts to crash under the pressure. The overflow could lead to unexpected behavior or a system crash, just like how an overloaded elevator could bring you to a grinding halt! An attacker could exploit this vulnerability to crash your browser, causing inconvenient interruptions or even worse, lead to potential remote control. While there's no known exploit yet, the risk of unexpected crashes is enough to warrant concern!
