Summary
A flaw was found in Google Chrome, specifically within its GPU component, where an uninitialized resource could be used. A remote attacker, after compromising the renderer process, could exploit this by crafting a malicious HTML page.
This could allow the attacker to read memory outside of the browser's security sandbox, leading to information disclosure. This Moderate impact information disclosure flaw in Chromium and QtWebEngine, affecting community projects, requires a prior renderer process compromise and user interaction with a specially crafted HTML page.
The need for these preconditions reduces the overall risk in typical Red Hat desktop deployments. Red Hat severity: Moderate — CVSS 6.8 (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:N/A:N).
Weakness: CWE-824.
