  "details" : [ "A flaw was found in the Linux kernel's rxrpc component. An unprivileged user can exploit this by providing an excessively large ticket length during key preparsing. This improper validation leads to an oversized token calculation when the key is subsequently read, triggering a system warning and potentially causing a Denial of Service (DoS)." ],
