CVE-2025-24213 is a type confusion vulnerability identified in Apple Safari, stemming from improper handling of floating-point values that leads to memory corruption. Type confusion occurs when a program mistakenly treats a piece of memory as a different type than intended, which can corrupt memory and enable arbitrary code execution or other malicious behavior. This vulnerability affects Safari versions up to 18.5 and related Apple operating systems including iOS 18.5, iPadOS 18.5 and 17.7.7, macOS Sequoia 15.5, tvOS 18.5, visionOS 2.5, and watchOS 11.5. The issue was addressed by Apple through improved float handling in these versions. The CVSS v3.1 score of 7.8 reflects a high severity, with an attack vector classified as local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The scope is unchanged (S:U), and the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H). This means an attacker who can trick a user into interacting with malicious content locally on the device could exploit this flaw to execute arbitrary code, escalate privileges, or cause denial of service. The vulnerability is categorized under CWE-843 (Type Confusion), a common class of memory safety errors. No public exploits are known yet, but the potential impact warrants immediate attention. The vulnerability affects a broad range of Apple platforms, reflecting the widespread use of Safari and Apple devices globally.

The potential impact of CVE-2025-24213 is significant for organizations and individuals relying on Apple Safari and related Apple operating systems. Successful exploitation can lead to arbitrary code execution, allowing attackers to run malicious code with the privileges of the user. This can result in full compromise of confidentiality, integrity, and availability of affected devices. Sensitive data could be stolen or manipulated, system stability could be undermined, and attackers could establish persistent footholds. Since Safari is a widely used browser on Apple devices, this vulnerability poses a risk to enterprises, government agencies, and consumers alike. The requirement for local access and user interaction somewhat limits remote exploitation, but social engineering or malicious websites could still trigger the vulnerability. Organizations with high-value targets using Apple ecosystems are particularly at risk, as attackers may leverage this flaw for espionage, data theft, or disruption. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, especially as attackers often develop exploits rapidly after disclosure.

To mitigate CVE-2025-24213, organizations and users should immediately update all affected Apple software to the patched versions: Safari 18.5, iOS 18.5, iPadOS 18.5 and 17.7.7, macOS Sequoia 15.5, tvOS 18.5, visionOS 2.5, and watchOS 11.5. Beyond patching, organizations should implement strict browser usage policies limiting Safari usage to trusted sites and consider deploying endpoint protection solutions capable of detecting anomalous memory corruption behavior. User education is critical to reduce the risk of social engineering attacks that could trigger the vulnerability. Network segmentation and application whitelisting can help contain potential exploitation. Monitoring for unusual process behavior or crashes related to Safari can provide early detection of exploitation attempts. Additionally, organizations should maintain up-to-date backups and incident response plans to quickly recover from potential compromises. Since the vulnerability requires user interaction, disabling or restricting the use of Safari in high-risk environments until patched can reduce exposure. Finally, security teams should stay alert for emerging exploit reports and threat intelligence updates related to this CVE.
