In response to the active exploit of an open high-severity zero-day vulnerability (CVE-2022-4262) in the Chrome web browser, Google has released an emergency security patch to address the issue.

Actively exploited Chrome zero-day vulnerability that allows attackers to execute an arbitrary code to take full control of the system remotely using the exploit that exists in the Wild.

Since the beginning of the year, Chrome has patched a total of nine zero-day vulnerabilities, including this one that was exploited in the wild. As a security patch, Google released Chrome 108.0.5359.94/.95 for the following major platforms:-

  • Windows
  • Mac
  • Linux

In the wild, an exploit for CVE-2022-4262 has been reported, and Google is aware of all these reports. As of now, Stable Desktop channel users have started to receive the new version as part of the rolling-out process. Within a few days or a few weeks, it will be reached by the entire user base.

Zero-Day Flaw Profile

  • CVE ID: CVE-2022-4262
  • Severity: High
  • Description: Type Confusion in V8
  • Reporting: It was reported on 2022-11-29

Successful exploitation of this zero-day bug leads to crashes of the browser by reading or writing memory out of buffer bounds.

V8, the open-source Google JavaScript engine written in C++ that powers both Chrome and other Chromium-based browsers* is an especially attractive target for attackers.

A type confusion vulnerability let the exploit to allocates or initializes a resource such as a pointer, object, or variable using one type, but it later accesses that resource using a type that is incompatible with the original type.

“Access to bug details and links may be kept restricted until a majority of users are updated with a fix.”

“We will also retain restrictions if the bug exists in a third-party library that other projects similarly depend on, but haven’t yet fixed.

“Google is aware that an exploit for CVE-2022-4262 exists in the wild.” Google Stated.
