CVE-2022-49295

This CVE concerns the Linux kernel nbd subsystem. The root cause is a race between module removal and handling of a netlink command in the nbd_cleanup() path, which could lead to a kernel NULL pointer dereference. The issue is mitigated by ensuring that genl_unregister_family() is called before c...
