Search: CVE-2025-21943

CVE-2025-21943 is a vulnerability in the Linux kernel's gpio aggregator driver where race conditions during module unload can cause system instability. The issue arises because driver attribute handlers do not hold module references, leading to potential use-after-free and list corruption. This can result in warnings and system instability when the gpio-aggregator module is rapidly loaded and unloaded concurrently with device creation.
