CVE-2026-84571

Application crash via crafted image processing

Published Sep 14, 2026 · Updated Sep 14, 2026

Buffer overflow in Apple platforms before 27 allows attackers to terminate an application by processing a maliciously crafted image. The image-processing component applies insufficient bounds checking to image data, but Apple has not identified the specific parser or function. A target application must process the crafted image, and the documented consequence is an application crash rather than code execution or data access.
