CVE-2024-27828 is a high-severity memory handling vulnerability in Apple IOSurfaceRoot, affecting iOS and iPadOS before 17.5, tvOS before 17.5, watchOS before 10.5, and visionOS before 1.2. The flaw is reported in IOSurfaceRootUserClient::s_create_shared_event, which delegates creation of an IOSurfaceSharedEvent object using user-controlled input. Repeated invocation with manipulated input can trigger a reference count leak on the IOSurfaceRoot object, causing retain operations without corresponding releases. This reference count corruption can destabilize kernel object lifetime management, leading to kernel panic conditions and creating a path to arbitrary code execution with kernel privileges. Apple addressed the issue through improved memory handling.
