CVE-2026-84627 · Severity: info · Published 2026-10-26

Apple's Accelerate Framework, a core component used across iOS, iPadOS, and macOS for performance-critical computing tasks, contains a buffer overflow vulnerability in image processing. An attacker can exploit this by crafting a malicious image file that, when processed by an application using the framework, causes heap corruption and potential application crash or system instability.
