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...
CVE-2022-49297
CVE-2022-49297 is a Linux kernel vulnerability related to the NBD (network block device) disconnect flow that could cause IO hangs when a device is disconnected. The issue occurs in the NBD path during disconnect and socket clearing, with inflight requests potentially not completing due to how NB...
