CVE-2018-4155: An issue was discovered in certain Apple products.

Security readout for executives and security teams

CVE-2018-4155 is an Apple CoreFoundation race condition affecting older iOS, macOS, tvOS, and watchOS releases. A maliciously crafted app could let an attacker run code with privileged access. Organizations with unmanaged or outdated Apple devices should treat this as a meaningful endpoint risk. Exposure is most likely on Apple devices that remain below iOS 11.3, macOS 10.13.4, tvOS 11.3, or watchOS 4.3. The bundle does not identify specific models, app distribution paths, or enterprise configurations that change exposure. Prioritize remediation where Apple devices handle sensitive data, privileged administration, or regulated workloads. The risk is not supported by active-exploitation evidence in this bundle, but privileged code execution from a crafted app is serious enough to drive timely patch compliance. Mitigation focus: Upgrade iOS devices to 11.3 or later.; Upgrade macOS systems to 10.13.4 or later.; Upgrade tvOS devices to 11.3 or later..
