How CVE-2025-24252 Works
CVE-2025-24252 is a critical use-after-free vulnerability affecting multiple Apple operating systems, including macOS, iOS, and tvOS. The flaw occurs when an application fails to properly manage memory allocations, allowing freed memory pointers to remain accessible. An attacker on the same local network can exploit this by sending maliciously crafted network packets, triggering memory corruption. This leads to arbitrary code execution or system crashes. The vulnerability stems from improper handling of objects in the networking stack, where a deallocated memory region is still referenced, enabling manipulation of process memory.
DailyCVE Form
Platform: Apple OS
Version: macOS Sequoia 15.4, Ventura 13.7.5, Sonoma 14.7.5
Vulnerability: Use-after-free
Severity: Critical
Date: 04/29/2025
What Undercode Say:
Exploitation:
- Craft malicious network packets targeting the vulnerable memory handler.
- Use a local network position to inject corrupted data.
3. Trigger memory reallocation to hijack execution flow.
Protection:
1. Apply Apple’s patches for macOS/iOS.
2. Disable unnecessary network services.
3. Use firewalls to restrict local network access.
Analytics:
- CVSS 4.0 Score: 9.8 (Critical)
- Attack Vector: Network-based
- Complexity: Low (No user interaction needed)
Commands:
- Check macOS version: `sw_vers -productVersion`
– List active network services: `netstat -tuln`
– Monitor memory processes: `vmmap`
Code Snippet (Detection):
include <stdio.h>
include <mach/mach.h>
int check_vulnerable_process() {
kern_return_t kr;
task_t task;
kr = task_for_pid(mach_task_self(), target_pid, &task);
if (kr != KERN_SUCCESS) return -1;
// Inspect memory regions for UAF indicators
return 0;
}
Mitigation Script (Firewall Rule):
sudo pfctl -ef /etc/pf.conf echo "block in from any to any port 5353" >> /etc/pf.conf
