We are tasked with synthesizing data from multiple intelligence sources about CVE-2026-64754 into a comprehensive analysis, returning a JSON object with specific fields. All fields must be plain text strings (paragraphs). We must use all provided data and cross-reference to add value. The output must be grounded in the input data, not invented.
Let's extract and analyze the provided data:
- CVE ID: CVE-2026-64754
- Description: "An out-of-bounds write issue was addressed with improved bounds checking. This issue is fixed in iOS 26.6 and 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. Processing a maliciously crafted file may lead to a denial-of-service."
- CVSS Score: 5.5, Vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H
- CWE: CWE-787 (Out-of-bounds Write)
- EPSS: 0.16% (percentile 5%) — low exploitation probability.
- Patch: Available from vendor (Yes). The fix is listed in the versions above.
- Reported by: apple
- CPE: apple:ios_and_ipados, apple:macos, apple:tvos, apple:visionos, apple:watchos — all with *:*:*:*:*:*:*. Specific version ranges given by EUVD: macOS 0 <15.7.8, macOS 0 <14.8.8, iOS and iPadOS 0 <26.6, macOS 0 <26.6, watchOS 0 <26.6, tvOS 0 <26.6, visionOS 0 <26.6. Note the macOS versions include Sequoia 15.7.8 fix, Sonoma 14.8.8, Tahoe 26.6. "macOS 0 <26.6" likely means macOS Tahoe (version 26.x). So affected products: all Apple operating systems before these fixed versions.
- Tags: Apple, Buffer Overflow, Ios And Ipados, Tvos, Visionos, Watchos, Memory Corruption. Also "Memory Corruption" tag is relevant.
- References: All are Apple support pages: 128066, 128067, 128068, 128069, 128070, 128071, 128072. Also ENISA EUVD ID: EUVD-2026-49465, with link to NVD.
Now, we need to produce each field as a paragraph.
- product_name: "1-3 words ONLY. The specific product or service name affected. Examples: 'Apache Tomcat', 'WordPress', 'Linux Kernel', 'nginx-ui', 'GoAnywhere MFT'. NOT

Attack Technique
A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.
Memory corruption occurs when a program writes data beyond the boundaries of allocated memory regions or accesses memory in unintended ways, violating the integrity of the process's address space.
