"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ncifs: validate idmap key payload length\n\nThe cifs.idmap key type stores its payload length in key->datalen, which\nis limited to U16_MAX. Accepting a larger key payload truncates the\nrecorded length and can make later users interpret the payload using\ninconsistent bounds.\n\nReject oversized preparsed payloads before allocating or copying them.\nThis keeps key->datalen consistent with the stored data for both inline\nand separately allocated idmap payloads."
