Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2023-2724 is a type confusion vulnerability in the V8 JavaScript engine within Google Chrome versions prior to 113.0.5672.126. The flaw, assigned CWE-843, permits heap corruption when a victim visits a specially crafted HTML page and carries a CVSS 3.1 base score of 8.8 reflecting high impact on confidentiality, integrity, and availability.

A remote attacker can exploit the issue without authentication by serving the malicious page, which triggers the type confusion and subsequent memory corruption. Successful exploitation could allow arbitrary code execution or other damaging actions within the browser process.

Chrome stable-channel updates released on 16 May 2023 address the vulnerability by advancing the browser to version 113.0.5672.126 or later; corresponding Fedora package advisories likewise direct users to apply the patched Chrome builds.

EPSS scores for the CVE reached a peak of 0.1522 after disclosure before settling at the current value of 0.1042, indicating that exploitation interest increased measurably in the weeks following public release.
