AnalysisAI
We are tasked with producing a JSON analysis for CVE-2026-64747. We must use all provided data, including EPSS, SSVC, patch availability, CPE, and tags. The vulnerability is a buffer overflow in Apple products, with an app potentially executing arbitrary code with kernel privileges. CVSS 7.8 (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H). CWE-120. Patch available from vendor. EPSS 0.19% (low). SSVC: Exploitation none, Automatable no, Technical impact total. KEV status? Not in input, so not KEV. POC? Not mentioned. Tags include RCE, Apple, Buffer Overflow, etc. Affected products: iOS 26.6, iPadOS 26.6, macOS Sequoia 15.7.8, macOS Sonoma 14.8.8, macOS Tahoe 26.6, tvOS 26.6, visionOS 26.6, watchOS 26.6. CPEs confirm. References are Apple support pages.
We must produce fields:
- product_name: 1-3 words, specific product. Since it spans many OSes, the "primary one"? The CVE description mentions iOS and iPadOS, macOS, tvOS, visionOS, watchOS. The common underlying component is likely the kernel or something. But the product is Apple's operating systems. Could say "Apple OS Family" or "Apple Kernel". The description says "An app may be able to execute arbitrary code with kernel privileges." So the vulnerability is in the kernel, accessible via an app. So product could be "Apple Kernel" or "Apple Operating Systems". But the instruction says "The specific product or service name affected. Examples: 'Apache Tomcat', 'WordPress', 'Linux Kernel'." So maybe "Apple Kernel". However, it's not explicitly named. The CPEs list specific products: ios_and_ipados, macos, tvos, visionos, watchos. So I'll use "Apple OS Family" but that is 3 words. "Apple Kernel" is 2 words. I'll go with "Apple Kernel" as the vulnerable component. The description isn't clear if it's the kernel itself or a system library, but "kernel privileges" suggests kernel execution. So "Apple Kernel" is appropriate.
- summary: 2-3 sentences, original synthesis, avoid starting with "A vulnerability". Start with impact verb a
