CVE-2026-76042 is a high-severity information disclosure vulnerability in the GPU component of Google Chrome prior to version 151.0.7922.169. The flaw is described as use of an uninitialized resource in GPU handling, which allows a remote attacker who has already compromised the renderer process to read memory outside the browser sandbox by inducing the target to process a crafted HTML page. The issue is associated with improper use of uninitialized memory or resources in a graphics-processing path, creating a condition where stale or unintended memory contents can become exposed across security boundaries.
