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.
