CVE-2024-7025Public exploitNetwork attack vector

Heap corruption via Layout integer overflow

Published Nov 27, 2024 · Updated Nov 27, 2024

Integer overflow in Google Chrome Layout before 129.0.6668.89 allows remote attackers to corrupt heap memory via crafted HTML. The Blink ruby-text justification path computes a string-view length from impl.length() minus offset without first validating the subtraction. Exploitation requires a user to open the page; the published testcase reaches a fatal assertion and crashes the renderer, while Google reports broader heap corruption.
