What it is

⚡ A pesky race condition in Chrome's V8 engine could let a remote attacker wreak havoc with crafted HTML — like sending in a bull when nobody's watching the china shop! Think of it as a busy restaurant where two servers are trying to collect the same order from the kitchen at the same time. If they're not careful, they might end up serving the wrong dish to the wrong table, causing chaos among hungry patrons. An attacker could exploit this race condition to cause heap corruption, potentially leading to arbitrary code execution. This could allow them to run malicious code on the user's machine, risking data theft or system compromise—absolutely devastating for your privacy!
