CVE-2025-39871

CVE-2025-39871 relates to the Linux kernel dmaengine idxd driver. The fix removes an improper idxd_free() call that could trigger a duplicate put_device() leading to refcount underflow and a use-after-free during module unload. The issue arises in idxd_remove() and during module exit when CONFIG_...
