“Earlier this week, Google released an emergency security update for the Chrome browser due to a vulnerability that is being actively exploited in the wild,” reports Hot Hardware:
On Friday, Google highlighted CVE-2023-2033, reported by Clément Lecigne of Google’s own Threat Analysis Group (TAG). This vulnerability is a ‘type confusion‘ bug in the JavaScript engine for Chromium browsers useing the V8 Javascript engine. In short, type confusion is a bug that allows memory to be accessed with the wrong type, allowing for the reading or writing of memory out of bounds. The CVE page says that an attacker could create an HTML page that allows the exploitation of heap corruption.
While there is no Common Vulnerability Scoring System (CVSS) score attached to the vulnerability yet, Google is tracking this as a “high” severity issue. This is likely due in part to the fact that “Google is aware that an exploit for CVE-2023-2033 exists in the wild.”
The article notes that Chrome updates are generally done automatically, but you can also check for updates by clicking Chrome’s three-dots menu in the top-right corner, then “Help” and “About Chrome.”
