CVE-2026-86869 · Severity: medium · CVSS 6.5 · Published 2026-09-14

Apple's Accelerate Framework, a core library used for image and media processing across iPhones, iPads, and Macs, contains an out-of-bounds memory write vulnerability. Processing a maliciously crafted image can crash the affected application, disrupting normal user operations. While the immediate impact is limited to app termination, out-of-bounds writes can be leveraged for more severe attacks in certain contexts.

## Technical details

CVE-2026-86869 is an out-of-bounds write vulnerability in the Accelerate Framework's image processing logic. The vulnerability exists due to insufficient bounds checking when handling image data. An attacker can craft a malicious image file that, when processed by any application using the Accelerate Framework, triggers a memory write beyond allocated buffer boundaries. The attack requires no special privileges or network access—only that a user or app process the malicious image. The vulnerability is fixed through improved bounds checking in iOS 26.7, iPadOS 26.7, and macOS Golden Gate 27, released September 14, 2026.

## Affected products

- Apple iOS before 26.7
- Apple iPadOS before 26.7
- Apple macOS before Golden Gate 27

## Timeline

- 2026-09-14: disclosed: Security advisory published alongside iOS 26.7, iPadOS 26.7, and macOS Golden Gate 27 release
- 2026-09-14: patched: Fixed in iOS 26.7, iPadOS 26.7, and macOS Golden Gate 27
