Out-of-bounds memory read via integer overflow
Published Apr 28, 2026 · Updated Apr 28, 2026
Integer overflow in ANGLE in Google Chrome on Windows before 147.0.7727.138 allows remote attackers to read out-of-bounds memory via crafted HTML. The public record identifies ANGLE as the affected component but does not disclose the calculation that overflows or the buffer access that follows. Opening attacker-controlled HTML is required, and successful exploitation discloses process memory without reported modification or service interruption.
