CVE-2025-40249

CVE-2025-40249 affects the Linux kernel GPIO cdev path. The issue arises when a GPIO change notification is emitted after the file descriptor’s reference count drops to zero but before the .release() callback is executed from the workqueue, leaving the descriptor potentially in use-after-free. Th...
