AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Remote crafted page with no privileges but mandatory victim interaction (UI:R); UAF heap corruption can yield full renderer compromise, so C/I/A:H, scope unchanged within the sandboxed renderer.

Use after free in Passwords in Google Chrome prior to 150.0.7871.47 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: Low)
AnalysisAI
Heap corruption via use-after-free in Google Chrome's Passwords component affects all desktop builds prior to 150.0.7871.47, letting a remote attacker who lures a victim to a crafted HTML page potentially achieve memory corruption and code execution in the renderer. The CVSS 3.1 vector (8.8) requires user interaction (visiting the page) but no privileges or authentication. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to actively load attacker-controlled HTML/JavaScript in a vulnerable Chrome build (before 150.0.7871.47) - the CVSS UI:R flag confirms user interaction (visiting or interacting with the crafted page) is mandatory, which is the primary limiting factor. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals conflict and should be weighed together. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a malicious web page containing JavaScript and DOM interactions crafted to trigger the use-after-free in Chrome's Passwords component, then lures a victim (via phishing link, malvertising, or a compromised site) into visiting it. When the victim's browser loads the page, the freed object is reused to corrupt the heap, giving the attacker a memory-corruption primitive that could be chained toward code execution in the renderer. … |
| Remediation | Vendor-released patch: update Google Chrome to 150.0.7871.47 or later via the Stable channel; the fix is delivered through Chrome's automatic updater, so ensure clients are not blocking updates and relaunch the browser to apply it (Help > About Google Chrome forces the check). … Detailed patch versions, workarounds, and compensating controls in full report. |
