Network delivery via crafted HTML page with mandatory active user navigation (UI:R); memory leakage justifies C:H with no integrity or availability impact whatsoever.
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 ANGLE in Google Chrome prior to 151.0.7922.72 allowed a remote attacker to obtain potentially sensitive information from process memory via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Uninitialized memory use in Chrome's ANGLE graphics layer (all versions prior to 151.0.7922.72) allows a remote attacker to read potentially sensitive data from the browser's process memory by delivering a crafted HTML page. The CVSS C:H rating reflects the theoretical confidentiality impact, but SSVC rates technical impact as only partial and exploitation as none, and EPSS sits at 0.31% (24th percentile), indicating low observed real-world exploitation probability. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation unconditionally requires a user to actively navigate to or be redirected to a crafted HTML page - the CVSS UI:R metric confirms this user interaction is mandatory and non-bypassable. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 3.1 scores this at 6.5 with vector AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N - network-reachable, low complexity, no privileges required, but user interaction mandatory. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a webpage containing crafted WebGL or GPU-accelerated rendering content designed to trigger specific uninitialized memory paths within Chrome's ANGLE graphics layer. When a targeted user visits the page using a vulnerable Chrome version, the browser processes the malicious graphics operations and exposes fragments of process memory - potentially including session tokens, cached credentials, or other in-memory data - accessible to attacker-controlled JavaScript. … |
| Remediation | Upgrade Google Chrome to version 151.0.7922.72 or later - this is the vendor-released patch as confirmed by the Chrome Releases advisory at https://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
