  "details": "In the Linux kernel, the following vulnerability has been resolved:  cifs: validate idmap key payload length  The cifs.idmap key type stores its payload length in key-\u003edatalen, which is limited to U16_MAX.  Accepting a larger key payload truncates the recorded length and can make later users interpret the payload using inconsistent bounds.  Reject oversized preparsed payloads before allocating or copying them. This keeps key-\u003edatalen consistent with the stored data for both inline and separately allocated idmap payloads.",
