A type confusion issue was addressed with improved memory handling. This issue is fixed in macOS Sequoia 15.2, iOS 18.2 and iPadOS 18.2. An attacker with user privileges may be able to read kernel memory.
The product allocates or initializes a resource such as a pointer, object, or variable using one type, but it later accesses that resource using a type that is incompatible with the original type.
The product reads data past the end, or before the beginning, of the intended buffer.
