How the CVE Works
CVE-2025-30445 is a type confusion vulnerability affecting Apple’s macOS, iOS, tvOS, and visionOS. The flaw occurs due to improper validation of object types in memory, allowing an attacker on the local network to manipulate data structures incorrectly. When exploited, this causes the targeted application to misinterpret object types, leading to unexpected termination or potential arbitrary code execution. The vulnerability stems from insufficient runtime checks in the affected OS components, enabling attackers to craft malicious network packets or files that trigger the confusion.
