CVE-2024-5842Network attack vector

Out-of-bounds memory read via UI use-after-free

Published Jun 11, 2024 · Updated Feb 13, 2025

Use-after-free in Google Chrome Browser UI before 126.0.6478.54 allows remote attackers to read out-of-bounds memory via crafted HTML. The restricted Chromium issue leaves the freed object and precise UI code path undisclosed, while the CVE record identifies invalid object lifetime handling in Browser UI. Exploitation requires specific user interface gestures on the crafted page, and the documented consequence is an out-of-bounds memory read rather than code execution.
