Uninitialized Use in GPU in Google Chrome on Android prior to 149.0.7827.197 allowed a remote attacker to obtain potentially sensitive information from process memory via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Uninitialized GPU memory use in Google Chrome on Android before 149.0.7827.197 exposes process memory contents to remote attackers without requiring authentication. An attacker who induces a user to load a crafted HTML page can read potentially sensitive data from Chrome's GPU process memory, consistent with the High confidentiality impact assigned in the CVSS vector. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the target to be running Google Chrome on Android with a version prior to 149.0.7827.197, and the user must actively navigate to a crafted HTML page under attacker control (UI:R). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 5.3 (Medium) reflects AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:N/A:N - remote delivery via a crafted HTML page, high attack complexity, no privileges required, but mandatory user interaction and no integrity or availability impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker registers or compromises a website and embeds a crafted HTML page designed to trigger the uninitialized GPU memory path in Chrome's Android rendering pipeline. A target user is directed to the page via a phishing message or malicious advertisement; upon rendering, the page causes Chrome to read and expose uninitialized GPU memory, potentially leaking sensitive fragments of previously processed data back to the attacker. … |
| Remediation | The vendor-released patch is Google Chrome 149.0.7827.197 for Android; users should update immediately via Google Play or Chrome's built-in update mechanism, as documented in the stable channel advisory at http://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0482630350.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
