  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ns390/zcrypt: Close speculative mem read possibility\n\nThe domain value is extracted from a given CCA or EP11 ioctl struct\nwhen a CPRB is about to be sent. Thus this is a user controlled value.\nUnder some special conditions (custom device node used, administrative\nload) this value is used as an array index after bounds checking, but\nwithout speculation barrier.\n\nAdd the missing array_index_nospec() call to prevent speculative\nexecution where this domain value is used.",
