Uninitialized Use in Canvas in Google Chrome on Android prior to 150.0.7871.47 allowed a remote attacker to obtain potentially sensitive information from process memory via a crafted HTML page. (Chromium security severity: Low)
AnalysisAI
Uninitialized memory read in the Canvas API of Google Chrome on Android (prior to 150.0.7871.47) exposes potentially sensitive process memory contents to remote attackers. Exploitation requires luring a target to a crafted HTML page, after which the uninitialized Canvas buffer may leak memory from the renderer process. …

Vulnerability AssessmentAI
| Exploitation | The victim must be running Google Chrome on an Android device with a version prior to 150.0.7871.47. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The NVD CVSS 3.1 score of 6.5 (Medium) reflects network reachability with no authentication, low complexity, and high confidentiality impact - but Chromium's own security team has independently classified this as Low severity, indicating the practical scope of leaked memory is likely limited, non-deterministic, or difficult to weaponize for high-value data extraction. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a crafted HTML page that triggers the uninitialized Canvas buffer read, causing Chrome's renderer process to return uninitalized heap memory to JavaScript. If a victim on Android Chrome (pre-150.0.7871.47) browses to this page - via phishing link, malicious ad, or compromised site - the attacker's script may read memory contents that could include fragments of prior allocations such as tokens, cookies, or other in-process data. … |
| Remediation | Update Google Chrome on Android to version 150.0.7871.47 or later, available via the Google Play Store or Chrome's built-in update mechanism. … Detailed patch versions, workarounds, and compensating controls in full report. |
