Memory disclosure via Tab Strip out-of-bounds read
Published Aug 26, 2021 · Updated Aug 3, 2024
Out-of-bounds read in Google Chrome before 92.0.4515.131 allows attackers to read process memory via a crafted HTML page. The Tab Strip component accesses memory outside its intended bounds when the page is handled with a malicious extension installed. Exploitation requires a user to install the extension and open the crafted page; the published record establishes memory disclosure but not data modification.
