Published Mar 11, 2026 · Updated Mar 11, 2026
Out-of-bounds read in V8 in Google Chrome before 146.0.7680.71 allows remote attackers to access memory via a crafted HTML page. Google has not published the vulnerable V8 code path or the incorrect bounds operation because the referenced issue remains restricted. Successful exploitation requires user interaction with the page and exposes memory outside the intended V8 bounds; further consequences are not publicly detailed.
