CVE-2024-7022Public exploitNetwork attack vector

Out-of-bounds memory access via invalid V8 graph node

Published Sep 23, 2024 · Updated Sep 25, 2024

Uninitialized use in V8 in Google Chrome before 123.0.6312.58 allows remote attackers to access out-of-bounds memory via crafted HTML. The WebAssembly imported-strings graph builder queried IsArrayNewSegment with an invalid node while generating unreachable operations instead of checking reachability first. A user must open the crafted page; the invalid access can interrupt browser processing, while public sources do not establish code execution or data disclosure.
