The overflow can corrupt heap structures when processing a maliciously crafted video file, potentially compromising the browser's integrity and allowing an attacker to execute code or crash the application. The issue is classified under CWE-190 and CWE-472, reflecting an integer calculation error that results in a buffer vulnerability.", "risk_and_exploitability": "With a CVSS score of 8.8, this vulnerability is considered high severity. The EPSS score of less than 1% and its absence from CISA's KEV catalog suggest that exploitation is currently uncommon, but the high potential impact warrants caution.
