Out of bounds read and write in GFX in Google Chrome prior to 148.0.7778.96 allowed a remote attacker to perform arbitrary read/write via malicious network traffic. (Chromium security severity: Medium)
AnalysisAI
Out-of-bounds read and write in the GFX component of Google Chrome prior to version 148.0.7778.96 allows remote attackers to perform arbitrary memory read and write operations through malicious network traffic. The vulnerability requires user interaction (clicking a link or visiting a malicious page) but does not require authentication. Chromium rated the security severity as Medium; CVSS 5.4 reflects moderate impact (confidentiality and integrity compromise without availability loss). No active exploitation confirmed in CISA KEV at time of analysis.
Technical ContextAI
The vulnerability exists in Chrome's Graphics (GFX) subsystem, which handles rendering operations and processes graphical data. GFX uses various libraries and protocols to parse and render web content, images, and GPU commands. Out-of-bounds access (CWE-125: Out-of-bounds Read) in GFX typically occurs when the parser fails to validate buffer boundaries before reading or writing memory, allowing an attacker to access adjacent memory regions. This can leak sensitive data (confidentiality) or corrupt memory (integrity). The affected CPE is cpe:2.3:a:google:chrome (all versions prior to 148.0.7778.96 on all platforms), indicating the flaw is platform-agnostic within Chrome releases.
RemediationAI
Vendor-released patch: Chrome 148.0.7778.96 and later. Users should update Chrome immediately via Settings > Help > About Google Chrome (automatic update prompt) or manually download from https://www.google.com/chrome/. Organizations can enforce updates via Chrome Enterprise policies or OS-level deployment mechanisms. No workarounds are documented; the out-of-bounds access is not conditional on configuration, so patching is the only mitigation. Note: Chrome's automatic update mechanism typically deploys patches within hours to days, so users with auto-update enabled may already be protected. Verify patch installation by checking chrome://version/ and confirming version ≥ 148.0.7778.96.
