CVE-2023-5849Network attack vector

Heap corruption via USB integer overflow

Published Nov 1, 2023 · Updated Apr 29, 2025

Integer overflow in Google Chrome's USB component before 119.0.6045.105 allows remote attackers to corrupt heap memory via crafted HTML. Google identifies the locus only as the USB component; restricted bug details leave the overflowing arithmetic and affected function undisclosed. A victim must load attacker-controlled HTML; successful exploitation corrupts browser-process memory and enables attacker-controlled execution within the sandbox.
