Loading vulnerability…
CVE-2024-36939 is an error-handling flaw in the Linux kernel NFS subsystem. During per-network-namespace initialization, nfs_net_init() did not handle a failure returned by rpc_proc_register(). Initialization could therefore be reported as successful even though the NFS RPC procfs registration had not completed. When that partially initialized network namespace was subsequently destroyed, nfs_net_exit() attempted to unregister a nonexistent procfs entry, triggering a kernel warning in procfs removal code. The upstream fix propagates and handles the registration error during NFS network-namespace initialization.
