Severity by source
Sources disagree (Medium–Critical)AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N
Renderer compromise prerequisite elevates AC to H; network delivery with required user interaction; confidentiality-only impact with no integrity or availability effect.
vuln.today treats the vendor’s rating as authoritative. A higher third-party CVSS (e.g. CISA-ADP) is shown for transparency but does not drive the headline severity.

Uninitialized Use in Media in Google Chrome on Windows prior to 151.0.7922.72 allowed a remote attacker who had compromised the renderer process to obtain potentially sensitive information from process memory via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Uninitialized memory disclosure in Google Chrome's Media component on Windows exposes process memory to attackers who have already achieved renderer process compromise. Versions prior to 151.0.7922.72 are affected. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation strictly requires that the attacker has already compromised the Chrome renderer process via a separate, independent vulnerability - this is an explicit prerequisite stated in the CVE description. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N) scores 6.5 and rates attack complexity as Low, but this conflicts materially with the description's explicit prerequisite of prior renderer process compromise - a high-complexity, multi-step precondition that AC:L does not capture. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker first exploits a separate renderer vulnerability in Chrome on Windows to achieve code execution within the sandboxed renderer process. From that position, they cause the renderer to load a crafted HTML page that triggers the uninitialized Media component path, reading stale heap data into an accessible buffer. … |
| Remediation | Vendor-released patch: 151.0.7922.72. … Detailed patch versions, workarounds, and compensating controls in full report. |
Threat intelligence, references, and detailed analysis are available after sign-in.
