CVE-2026-8553 Google CVE debrief

CVE-2026-8553 is a use-after-free vulnerability in the GPU component of Google Chrome, rated High severity by Chromium with a CVSS 3.1 score of 3.1 (Low). The vulnerability affects Chrome versions prior to 148.0.7778.168. A remote attacker who has already compromised the renderer process can exploit this flaw to perform an out-of-bounds memory write via a crafted HTML page. The use-after-free condition (CWE-416) in GPU processing creates a memory corruption primitive that could enable further compromise within the browser sandbox. The attack requires user interaction (UI:R) and high attack complexity (AC:H), with no privileges required (PR:N) and no impact to confidentiality or availability, but with low integrity impact possible. Google addressed this vulnerability in the Chrome stable channel update released May 12, 2026.
