CVE-2026-87555Network attack vector

Memory disclosure via uninitialized GPU resource

Published Sep 9, 2026 · Updated Sep 9, 2026

Uninitialized GPU resource use in Google Chrome for Android before 153.0.8010.36 allows remote attackers to read memory via crafted HTML. The GPU component uses a resource before initializing it, causing memory outside the browser sandbox to become readable. Opening attacker-crafted HTML is required, and the published impact is limited to confidentiality; further implementation details remain access-restricted.
