CVE-2024-44297Network attack vector

Denial of service via inadequate message bounds

Published Oct 28, 2024 · Updated Apr 2, 2026

Bounds-checking failure in ImageIO in Apple iOS, iPadOS, macOS, tvOS, visionOS, and watchOS allows remote attackers to cause denial of service. ImageIO processes a maliciously crafted message without adequate bounds checks, permitting an out-of-range access during message handling. The target must process the crafted message, and the documented consequence is availability loss without reported data disclosure or modification.
