Process crash via out-of-bounds image write
Published Sep 14, 2026 · Updated Sep 14, 2026
Out-of-bounds write in Apple image processing on iOS, iPadOS, macOS, tvOS, visionOS, and watchOS allows attackers to crash a process. The undisclosed image-processing component writes beyond a buffer when it handles a maliciously crafted image because its bounds checks are insufficient. Exploitation requires a crafted image to be processed; the published impact is unexpected process termination, with no reported code execution or data exposure.
