This vulnerability involves a use-after-free condition in the V8 engine of Google Chrome versions before 153.0.8010.36.

No CVSS score or explicit remediation level is provided in the source data, though a vendor advisory is linked for updates.

Successful exploitation allows remote attackers to execute arbitrary code inside the Chrome sandbox, potentially compromising the security boundary of the browser.
