Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Timely flaw remediation through patching directly prevents exploitation of this buffer overflow vulnerability, as evidenced by the specific macOS updates that address it.
Information input validation with bounds checking directly mitigates buffer overflows by ensuring inputs do not exceed allocated memory, matching the CVE's root cause and fix.
Memory protection mechanisms like address space layout randomization and data execution prevention provide secondary mitigation against buffer overflow exploitation even if the flaw is present.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
The CVE describes a remotely exploitable buffer overflow (CWE-120) in macOS OS software with network vector, no authentication, no privileges, and no user interaction required, directly enabling exploitation of remote services for code execution or system impact as described in T1210.
NVD Description
A buffer overflow was addressed with improved bounds checking. This issue is fixed in macOS Sequoia 15.4, macOS Sonoma 14.7.5, macOS Ventura 13.7.5. An app may be able to cause unexpected system termination.
Deeper analysisAI
CVE-2025-24266 is a buffer overflow vulnerability (CWE-120) addressed through improved bounds checking in macOS. It affects macOS Sequoia versions prior to 15.4, macOS Sonoma versions prior to 14.7.5, and macOS Ventura versions prior to 13.7.5. The vulnerability carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating critical severity.
A remote attacker can exploit this vulnerability over the network with low attack complexity, requiring no privileges, authentication, or user interaction. Exploitation by an app can cause unexpected system termination, with potential for high impacts on confidentiality, integrity, and availability.
Apple security updates macOS Sequoia 15.4, macOS Sonoma 14.7.5, and macOS Ventura 13.7.5 resolve the issue. Practitioners should prioritize patching affected systems, with further details in Apple's advisories at https://support.apple.com/en-us/122373, https://support.apple.com/en-us/122374, https://support.apple.com/en-us/122375, and full disclosure postings at http://seclists.org/fulldisclosure/2025/Apr/10 and http://seclists.org/fulldisclosure/2025/Apr/8.
