Published Apr 28, 2026 · Updated Apr 28, 2026

Out-of-bounds memory access in Tint in Google Chrome before 147.0.7727.138 allows remote attackers to access memory via crafted HTML. The public record identifies only an inappropriate implementation in Tint; the restricted Chromium issue does not disclose the faulty operation or affected code path. A user must open the attacker-controlled page, and the published impact is limited to out-of-bounds memory access rather than confirmed code execution.
