When the affected operating systems or browsers render the offending page, a memory handling error causes the browser or related system process to terminate abruptly. The result is a denial of service to the user, potentially interrupting browsing sessions or other tasks that rely on the vulnerable application. No evidence of code execution or privilege escalation is provided in the description, so the impact is limited to service disruption only.", "risk_and_exploitability": "The probability of exploitation is low, with an EPSS score of less than 1% and no entry in the CISA KEV catalog. The likely attack vector is delivery of malicious web content, requiring user interaction or a compromised website to load the vulnerable browser logic. While the flaw can cause a crash, it does not provide an attacker with code execution capabilities or broader system compromise. The overall risk is moderate for exposed users but low for automated exploitation efforts."}}}}, "created": "2026-03-25T11:36:50.492522+00:00", "updated": "2026-03-26T12:18:17.532238+00:00", "vendors": ["apple", "apple$PRODUCT$ios_and_ipados", "apple$PRODUCT$macos", "apple$PRODUCT$safari", "apple$PRODUCT$visionos"]}
