An input validation issue that may have allowed attackers on the local network to cause unexpected system terminations or corrupt process memory has been fixed. Users are advised to update to the latest versions of visionOS, iOS, iPadOS, macOS Sequoia, watchOS, and tvOS.

Body

A recent vulnerability, documented under the code CVE-2025-24126, has been discovered affecting various software versions, including visionOS 2.3, iOS 18.3 and iPadOS 18.3, macOS Sequoia 15.3, watchOS 11.3, and tvOS 18.3. It should be noted that this vulnerability could have led to attackers causing system corruption or termination from within the local network.

Referring to the official CVE documentation (!link to CVE-2025-24126), the issue was a result of an input validation issue in these software versions, which have now been addressed.

More specifically, the vulnerability stemmed from improper management of user-provided data in the system. For example, the code snippet below demonstrates a simplified scenario where a program receives an input from the user:

#include <stdio.h>
#include <string.h>

int main() {
    char input[100];

    printf("Enter your data: ");
    scanf("%s", &input);

    printf("You entered: %s", input);
}

In this example, the lack of input validation may push the program to accept unintended inputs, potentially causing security issues or incorrect program behavior.

To fix this input validation issue and mitigate the risks caused by this vulnerability, it is imperative that users update their software versions to visionOS 2.3, iOS 18.3 and iPadOS 18.3, macOS Sequoia 15.3, watchOS 11.3, and tvOS 18.3. Updates can be accessed through the following links:

- visionOS 2.3 update: visionOS update page
- iOS 18.3 update: iOS update page
- iPadOS 18.3 update: iPadOS update page
- macOS Sequoia 15.3 update: macOS update page
- watchOS 11.3 update: watchOS update page
- tvOS 18.3 update: tvOS update page

It's worth noting that the potential impact of CVE-2025-24126 was relatively high, seeing that an attacker within the local network could have exploited this vulnerability to create unintended behavior, such as corrupting process memory or causing the system to crash. However, now that the fix has been implemented, users are urged to act responsibly and install the updates.

Conclusion

CVE-2025-24126 was an important security concern affecting multiple software versions, specifically visionOS 2.3, iOS 18.3 and iPadOS 18.3, macOS Sequoia 15.3, watchOS 11.3, and tvOS 18.3. With the input validation issue now resolved, users must update their systems as soon as possible to minimize the risks associated with this vulnerability.
