CVE-2025-21731

The Linux kernel contains a use-after-free (UAF) vulnerability in the nbd (Network Block Device) driver. The flaw occurs because the nbd_genl_disconnect() function flushes work items and releases references, but if a reference is temporarily grabbed, it remains non-zero. Subsequent calls to nbd_g...
