CVE-2022-49300

CVE-2022-49300 affects the Linux kernel nbd subsystem. A race occurs when the nbd module is removed: nbd_genl_connect() may call nbd_alloc_config() concurrently, and although try_module_get() can fail, nbd_alloc_config() previously did not handle that. This can cause leakage of nbd_config and rel...
