A kernel memory-safety vulnerability in Apple iOS, iPadOS, and macOS Tahoe could allow a local application to trigger unexpected system termination or corrupt kernel memory. Apple attributed the issue to improper memory handling in the Kernel component and fixed it in iOS 26.6.1, iPadOS 26.6.1, and macOS Tahoe 26.6.2 through improved memory handling. The available information indicates a local app-to-kernel attack surface and a memory corruption condition affecting kernel stability and integrity, but does not provide the specific vulnerable function or a more precise root-cause classification beyond memory handling.
