Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2024-27856 is a code injection vulnerability (CWE-94) affecting Apple's Safari browser and operating systems including iOS prior to 16.7.8 and 17.5, iPadOS prior to 16.7.8 and 17.5, macOS Sonoma prior to 14.5, tvOS prior to 17.5, visionOS prior to 1.2, and watchOS prior to 10.5. The issue occurs during file processing, potentially leading to unexpected application termination or arbitrary code execution, and carries a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).
An attacker with local access can exploit this vulnerability with low complexity and no required privileges, though user interaction is necessary, such as tricking a user into opening a malicious file. Successful exploitation enables high-impact outcomes, including arbitrary code execution, compromise of confidentiality, integrity, and availability on the targeted device.
Apple advisories indicate the vulnerability was addressed through improved checks in Safari 17.5, iOS 16.7.8 and iPadOS 16.7.8, iOS 17.5 and iPadOS 17.5, macOS Sonoma 14.5, tvOS 17.5, visionOS 1.2, and watchOS 10.5. Mitigation requires updating to these versions or later, with further details in support documents such as https://support.apple.com/en-us/120896, https://support.apple.com/en-us/120898, https://support.apple.com/en-us/120901, https://support.apple.com/en-us/120902, and https://support.apple.com/en-us/120903.

V1.3.1
Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation finds code paths that accept and execute externally influenced strings.
Input validation directly stops untrusted data from being used to construct executable code without neutralization.
Least privilege limits the damage an injected code fragment can perform once executed.
Requiring documented secure development standards and tools enforces use of safe code-generation APIs and escaping.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
PR.PS-06's SDLC practices directly target injection flaws via secure coding and testing (mostly), yet as a single broad outcome it leaves many code-generation specifics unaddressed (partial).
PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Banning unapproved code samples and unauthenticated web services, combined with secure-coding standards and SAST, prevents the dynamic generation or inclusion of attacker-supplied code.
Controls that restrict unauthorized or malicious code from being introduced via external networks or removable media limit opportunities for an attacker to inject and execute arbitrary code.
