Out-of-bounds memory access via crafted HTML
Published Jun 19, 2024 · Updated Feb 13, 2025
Out-of-bounds memory access in V8 WebAssembly in Google Chrome before 126.0.6478.114 allows remote attackers to access memory via crafted HTML. Google identifies the locus as V8's WebAssembly implementation but has not published which operation mishandles untrusted module data. A user must open the crafted page; successful triggering causes out-of-bounds access inside the browser process, with no reported sandbox escape.
