CVE-2026-2315Network attack vector

Out-of-bounds memory access via crafted HTML

Published Feb 11, 2026 · Updated Feb 11, 2026

Memory-safety failure in WebGPU in Google Chrome before 145.0.7632.45 allows remote attackers to trigger out-of-bounds access via crafted HTML. The Chromium issue is access-restricted, so Google has not disclosed the faulty WebGPU operation or the validation error that permits the access. A user must open the crafted page; the public record does not establish whether the access reads or writes memory, crashes Chrome, or escapes its sandbox.
