Executive brief
The Accelerate Framework, a core component of macOS used for processing images and multimedia files, contains an integer overflow vulnerability. An attacker could exploit this by crafting a malicious image file that, when processed by the system or applications using this framework, could cause the application to crash or potentially leak sensitive memory contents.
Technical details
An integer overflow vulnerability exists in Apple's Accelerate Framework, addressed with improved input validation. The flaw occurs during the processing of maliciously crafted image files. The vulnerability can be triggered when an application processes a specially crafted image without proper integer bounds checking, leading to memory corruption. Attack vectors include local processing of untrusted image files. An attacker could achieve denial-of-service through application crash or potentially disclose memory contents. The vulnerability is fixed in macOS Golden Gate 27 released on September 14, 2026.
