Process-memory disclosure via malicious browser extension
Published Jul 1, 2026 · Updated Jul 1, 2026
Out-of-bounds read in V8 in Google Chrome before 150.0.7871.46 allows attackers to read process memory via a crafted extension. Google has not disclosed the specific V8 operation that reads beyond its intended bounds, and the referenced Chromium issue remains access-restricted. A user must install the malicious extension; the reported consequence is process-memory disclosure without integrity or availability impact.
