Out of bounds read in Codecs in Google Chrome 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
Out-of-bounds read in Google Chrome's Codecs component (prior to 150.0.7871.47) enables remote attackers to leak sensitive data from renderer process memory by delivering a crafted HTML page. The CVSS C:H rating reflects meaningful exposure of in-process data such as session tokens or credentials, though Chromium's own team assessed this as Medium severity, and the sandbox boundary (S:U) limits blast radius to the renderer. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to actively visit an attacker-controlled or compromised HTML page using an unpatched version of Google Chrome prior to 150.0.7871.47 - user interaction (UI:R) is a hard requirement; passive exposure is not sufficient. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 6.5 and Chromium's own Medium severity rating are consistent with one another: the UI:R constraint substantially reduces exploitability compared to fully drive-by scenarios. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a malicious webpage embedding specially crafted audio or video media content designed to trigger a bounds-check failure in Chrome's Codecs decoder, then lures a target into visiting the URL via phishing email or a compromised advertisement. Upon page load, the out-of-bounds read leaks bytes from the renderer process's memory, which the malicious page's JavaScript can capture and exfiltrate, potentially exposing session tokens or other sensitive in-process data. … |
| Remediation | Update Google Chrome to version 150.0.7871.47 or later using the stable channel update documented at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
