A resource-exhaustion vulnerability was found in the kernel, where an unprivileged process could allocate and accumulate far more file descriptors than the process' limit. A local, unauthenticated user could exploit this flaw by sending file descriptors over a Unix socket and then closing them to keep the process' fd count low, thereby creating kernel-memory or file-descriptors exhaustion (denial of service).
