Executive brief
Apple's Accelerate Framework processes images for iOS, iPadOS, macOS, and related platforms. A maliciously crafted image can cause unexpected app termination due to an out-of-bounds write vulnerability. While the impact is limited to denial of service, this could disrupt user operations if exploited.
Technical details
An out-of-bounds write vulnerability exists in Apple's Accelerate Framework image processing component. The vulnerability occurs when processing maliciously crafted image files, allowing memory to be written outside valid bounds due to insufficient bounds checking. The attack vector requires user interaction (processing a crafted image), and no authentication is required. An attacker can trigger unexpected process termination and potentially cause denial of service. The vulnerability has been patched in iOS 27, iPadOS 27, macOS Golden Gate 27, macOS Sequoia 15.8, macOS Tahoe 26.7, tvOS 27, visionOS 27, and watchOS 27.
