Type Confusion Vulnerability in Safari and iOS Products

CVE-2025-43541

What is CVE-2025-43541?

CVE-2025-43541 is a type confusion vulnerability affecting multiple Apple products, including Safari and various iOS and macOS versions. Type confusion vulnerabilities occur when a program mistakenly interprets a variable of one type as another type, leading to unexpected behaviors. In this case, the vulnerability arises from the processing of maliciously crafted web content, which can cause the Safari browser to crash unexpectedly. This issue poses a significant risk for organizations relying on Apple’s ecosystem, as it can result in denial of service and disrupt business operations. Affected versions have received patches to enhance state handling, providing organizations with an urgent incentive to ensure their systems are updated to the latest software versions.

Potential impact of CVE-2025-43541

1. Denial of Service: The vulnerability can lead to unexpected crashes in the Safari browser, causing interruptions in user access and potentially halting critical business processes that rely on web-based applications.

2. Security Risks from Malicious Content: Since the vulnerability is triggered by processing crafted web content, it exposes users to risks from malicious websites, which can further lead to exploitation by other attack vectors if left unaddressed.

3. Operational Disruption: Organizations using affected Apple products may face operational challenges if their users experience frequent crashes, resulting in decreased productivity and increased IT support costs to address the implications of this vulnerability.
