DescriptionCVE.org

Uninitialized Use in WebXR 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: Medium)

AnalysisAI

Uninitialized memory read in Google Chrome's WebXR subsystem on Android (versions prior to 150.0.7871.47) enables remote attackers to leak sensitive contents from process memory by inducing a victim to visit a crafted HTML page. The root cause is CWE-457 (use of an uninitialized variable) within the WebXR implementation, meaning memory buffers are consumed before being properly zeroed or assigned, exposing whatever residual data the process held. …

Vulnerability AssessmentAI

Exploitation	The victim must be using Google Chrome on Android (not desktop or iOS) running a version strictly below 150.0.7871.47. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment	The CVSS 3.1 score of 6.5 (Medium) with vector AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N captures the core risk profile accurately: the attack is network-delivered and low-complexity, requiring no authentication, but does demand active user interaction (UI:R) - the victim must navigate to a crafted page. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario	An attacker hosts a crafted HTML page containing malicious WebXR session code designed to trigger an uninitialized buffer read in Chrome's Android WebXR implementation. When an Android Chrome user visits the page - for instance, via a phishing link, malvertising, or a compromised site - the uninitialized memory contents are surfaced to the attacker-controlled JavaScript context and can be exfiltrated. …
Remediation	Update Google Chrome on Android to version 150.0.7871.47 or later. … Detailed patch versions, workarounds, and compensating controls in full report.
