gpio aggregator

The gpio-aggregator tag on WindowsForum.com covers Linux kernel security and stability issues related to the gpio-aggregator driver. A recent thread discusses CVE-2025-21943, a race condition that occurs when module unload races with driver attribute handlers, potentially leaving platform devices dangling and destabilizing the host. The fix involves holding a module reference via try_module_get() in attribute handlers that access module-global state during device registration or deletion. This tag is relevant for system administrators and developers managing affected kernels and distributions, emphasizing availability and stability priorities.
