A potential security threat has recently been identified and is being addressed by Apple. The threat is commonly referred to as CVE-2024-23225 and is linked to a severe memory corruption issue that can lead to kernel memory protections being bypassed. As iOS and iPadOS are some of the most widely used operating systems globally, this vulnerability could have concerning implications. Even though Apple has already addressed the issue in iOS 16.7.6, iPadOS 16.7.6, iOS 17.4, and iPadOS 17.4, it appears that the vulnerability might already have been exploited.

Details of CVE-2024-23225

Essentially, CVE-2024-23225 is a vulnerability in the iOS and iPadOS kernel that leads to memory corruption due to a lack of validation. An attacker with the ability to read and write kernel memory arbitrarily can take advantage of this vulnerability to bypass kernel memory protections put in place by Apple. This, in turn, could lead to unauthorized access to sensitive data or perform unwanted actions on the compromised device.

An attacker, to exploit the vulnerability, could use code like the following

/* Pseudo-code example of kernel read and write capability exploit */
void *arbitrary_kernel_read(uint64_t addr) {
   // Read the target address
   return read_data_from_kernel();

void arbitrary_kernel_write(uint64_t addr, void *data, size_t len) {
   for (size_t i = ; i < len; i++) {
      // Write the data to the target address
      trigger_vulnerability(addr + i);

This kind of exploit might not be apparent during regular device usage but could potentially lead to more significant security breaches if left unaddressed.

Apple's Response

Upon becoming aware of this issue, Apple worked swiftly to address it, releasing patches in iOS 16.7.6, iPadOS 16.7.6, iOS 17.4, and iPadOS 17.4. These patches focus on improving memory validation, thereby preventing potential attacks.

What Users Need to Do

If you're using an iOS or iPadOS device and worry about potential vulnerabilities, it's crucial that you update your device to the latest available versions (iOS 16.7.6, iPadOS 16.7.6, iOS 17.4, or iPadOS 17.4) to mitigate the risks.

Exploit Details

It's crucial to understand that this exploit might already be in circulation, as Apple is aware of reports indicating the vulnerability might have been exploited in the wild. As a user, the best form of protection is making sure you keep your device updated and follow reliable sources for software updates. Additionally, avoid installing software from untrusted sources to safeguard your devices against potential exploits.


While the CVE-2024-23225 vulnerability is indeed a serious security concern, Apple has been quick to address and patch the issue. Users should update their devices promptly and always stay informed about potential vulnerabilities inherent in the devices they use daily.
