vulnerability analysis and mitigation

CVE-2022-3075 is a high-severity vulnerability discovered in Google Chrome's Mojo component prior to version 105.0.5195.102. The vulnerability was reported by an anonymous researcher on August 30, 2022, and was publicly disclosed on September 2, 2022. It affects the data validation process in Mojo, which is a collection of runtime libraries providing platform-agnostic abstraction of common IPC primitives (Chrome Release, Security Online).

The vulnerability is classified as an insufficient data validation issue in the Mojo component of Google Chrome. It received a CVSS v3.1 base score of 9.6 (CRITICAL) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H. The vulnerability is related to improper input validation (CWE-20) that could allow an attacker to perform unauthorized actions (NVD).

The vulnerability allows a remote attacker who has compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. This could lead to the execution of arbitrary code outside the browser's security sandbox, potentially compromising the underlying system (CVE).

Google released a security update to address this vulnerability in Chrome version 105.0.5195.102 for Windows, Mac, and Linux platforms. Users are strongly advised to update their Chrome browsers to this version or later. The update was rolled out over several days/weeks following the initial release (Chrome Release, Security Online).
