Use after free in Views in Google Chrome on on Mac prior to 152.0.7977.65 allowed a remote attacker to execute arbitrary code outside the sandbox via a crafted HTML page. (Chromium security severity: Medium)

AnalysisAI

Sandbox-escaping remote code execution in Google Chrome on macOS (versions prior to 152.0.7977.65) stems from a use-after-free in the Views UI component, letting a remote attacker who lures a victim to a crafted HTML page run arbitrary code outside the browser sandbox. Google has shipped a fixed Stable channel build, and there is no public exploit identified at time of analysis. …

Vulnerability AssessmentAI

Exploitation Exploitation requires the victim to actively open or visit an attacker-crafted HTML page in Google Chrome on macOS (CVSS UI:R user interaction), and the target must be running a Chrome build older than 152.0.7977.65. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The signals here conflict and must be weighed together rather than taken at face value. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker hosts a crafted HTML page and lures a macOS Chrome user to open it via a phishing link or malicious ad. When the page renders, it triggers the use-after-free in the Views component, corrupts heap memory, and executes attacker-controlled code outside the browser sandbox on the victim's Mac. …
Remediation Vendor-released patch: 152.0.7977.65 - upgrade Google Chrome on macOS to 152.0.7977.65 or later via the Stable desktop channel, then fully restart the browser so the update takes effect (Chrome auto-updates but a relaunch is required to load the patched binary). … Detailed patch versions, workarounds, and compensating controls in full report.
