CVE-2024-2884Network attack vector

Memory disclosure via V8 out-of-bounds read

Published Jul 16, 2024 · Updated Mar 19, 2025

Out-of-bounds read in V8 in Google Chrome before 121.0.6167.139 allows remote attackers to read memory via a crafted HTML page. Public records identify V8 as the locus but do not disclose the affected function, input field, or missing bounds check because the Chromium issue requires sign-in. A user must load attacker-controlled HTML; published impact is limited to memory disclosure, with no reported write or code execution.
