Deeper analysis

CVE-2023-4430 is a use-after-free vulnerability in the Vulkan component of Google Chrome versions prior to 116.0.5845.110. The flaw, assigned CWE-416 and rated High severity by Chromium, can result in heap corruption when processing a specially crafted HTML page. It carries a CVSS 3.1 base score of 8.8 reflecting network attack vector, low complexity, and no required privileges beyond user interaction.

A remote attacker can exploit the issue by persuading a victim to visit a malicious web page, after which successful exploitation may allow arbitrary code execution or other impacts on confidentiality, integrity, and availability within the browser process.

Chrome stable channel updates released on 2023-08-23 address the vulnerability by advancing to version 116.0.5845.110; downstream distributions such as Fedora have issued corresponding package updates to apply the same fix.
