Out of bounds read in Fonts in Google Chrome prior to 148.0.7778.96 allowed a remote attacker to perform an out of bounds memory read via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Out-of-bounds memory read in Google Chrome's font handling allows remote attackers to leak sensitive information via a crafted HTML page when users visit a malicious website. Chrome versions prior to 148.0.7778.96 are affected. The vulnerability requires user interaction (clicking a link or visiting a page) but occurs over the network without authentication. Information disclosure risk is limited (CVSS C:L) with no impact on integrity or availability, but the Chromium security severity designation of High indicates concern about potential information leakage in real-world exploitation.
Technical ContextAI
The vulnerability is a classic out-of-bounds read (CWE-125) in Chrome's font rendering subsystem. When processing crafted font data embedded in or referenced by an HTML page, the font parser fails to properly validate buffer boundaries before reading memory. This allows an attacker to read adjacent memory regions, potentially disclosing browser process memory contents such as heap data, pointers, or other sensitive information. The attack occurs during HTML parsing and font loading, which are inherent to normal web browsing, making this a client-side attack vector executed by the Chromium rendering engine.
RemediationAI
Upgrade Google Chrome to version 148.0.7778.96 or later immediately. Users can update via Settings > About Google Chrome, which triggers automatic download and installation on next restart. Organizations managing Chrome deployments should push version 148.0.7778.96 or later via their device management policies. No workarounds exist for this rendering-engine vulnerability; patching is the only mitigation.
