How CVE-2025-24269 Works
CVE-2025-24269 is a critical memory-handling flaw in macOS Sequoia before version 15.4. A malicious app can exploit improper memory management in the kernel or system services, leading to unexpected termination (kernel panic). The vulnerability occurs when crafted input triggers a memory corruption scenario, such as use-after-free or buffer overflow, during system API calls. Attackers may chain this with privilege escalation techniques to destabilize the OS. Apple patched it by implementing additional bounds checks and memory validation.
