CVE-2022-0114Network attack vector

Memory disclosure via Web Serial out-of-bounds read

Published Feb 11, 2022 · Updated Aug 2, 2024

Out-of-bounds memory access in Google Chrome before 97.0.4692.71 allows remote attackers to read memory via crafted HTML and a virtual serial port. SerialPortUnderlyingSink::WriteData reads beyond the intended buffer while processing data sent through Blink's Web Serial implementation. A user must open the crafted page while a virtual serial port driver is present; successful exploitation exposes browser-process memory.
