The flaw permits a user with local device access to stop the emergency sharing process, potentially preventing the timely transmission of critical information to emergency services. The vulnerability does not grant additional privileges or data exfiltration; its primary impact is denial of a safety\u2010related feature.", "risk_and_exploitability": "The CVSS score of 6.9 reflects moderate impact and local execution, while the EPSS score of less than 1% indicates a very low likelihood of exploitation at this time. The vulnerability is not currently listed in the CISA KEV catalog, further suggesting limited active exploitation.
