In this case, the issue could allow a remote attacker to cause a denial of service on devices running the affected versions of iOS, iPadOS, macOS Tahoe, tvOS, visionOS, and watchOS.
How can this vulnerability impact me? :
The primary impact of this vulnerability is that a remote attacker may be able to cause a denial of service on affected devices. This means that the attacker could potentially disrupt the normal operation of your device, causing it to crash or become unresponsive.
