CVE-2025-11215Network attack vector

Memory disclosure via off-by-one V8 read

Published Nov 6, 2025 · Updated Nov 6, 2025

Out-of-bounds read in V8 in Google Chrome before 141.0.7390.54 allows remote attackers to read process memory via a crafted HTML page. V8 mishandles a boundary calculation by one element when processing attacker-controlled page content, causing a read beyond the intended buffer. A user must load the crafted page; published scoring limits the direct consequence to low confidentiality loss without integrity or availability impact.
