AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Network-delivered crafted page needs no privileges (PR:N) but requires the victim to open it (UI:R); memory corruption yields High C/I/A within a renderer-confined, unchanged scope (S:U).

Use after free in Ozone in Google Chrome prior to 150.0.7871.115 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: Critical)
AnalysisAI
Remote heap corruption in Google Chrome desktop before 150.0.7871.115 stems from a use-after-free (CWE-416) in Ozone, the platform abstraction layer that mediates windowing, graphics, and input. A remote attacker who lures a victim into loading a crafted HTML page can trigger the freed-memory reuse and potentially achieve renderer-level code execution; Chromium rates the underlying flaw Critical. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to open or render an attacker-controlled crafted HTML page in a vulnerable Chrome desktop build (before 150.0.7871.115) - the CVSS UI:R metric confirms user interaction is mandatory and is the primary limiting factor. … 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:H/A:H, base 8.8) shows a network-reachable, low-complexity, unauthenticated flaw whose only gating factor is user interaction - the victim must open a malicious page, which is trivial to induce for a browser. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts or injects (for example via a malicious ad) a crafted HTML page and lures a Chrome user to it through a link or compromised site. Rendering the page drives Ozone to free and then reuse an object, giving the attacker heap corruption and a potential path to code execution in the renderer. … |
| Remediation | Vendor-released patch: 150.0.7871.115 - update Google Chrome desktop to 150.0.7871.115 or later via the Chrome Releases stable channel update (https://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_01162222768.html) and relaunch the browser, since Chrome only applies staged updates on restart. … Detailed patch versions, workarounds, and compensating controls in full report. |
