      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ns390/zcrypt: Fix missing mem scrub at clear key import in cca_clr2cipherkey()\n\nThe helper function _ip_cprb_helper() uses internal buffer memory for\nbuilding and processing CPRBs. After use this buffer was never\nscrubbed which could lead to leaving for example clear key material in\nmemory which could be exposed via tricky reuse of this same memory.\n\nExtend the _ip_cprb_helper() function with another parameter 'scrub'\nused to steer scrubbing of this buffer. So now the caller has the\nopportunity to decide if scrubbing is needed or not.\n\nExtend the clear key to secure key token import process in function\ncca_clr2cipherkey() to tell the helper function from above to scrub\nthe cprb buffer when the clear key value is part of the request data.\n\nAdd explicit scrubbing on return from function cca_clr2cipherkey() for\nthe random EXOR buffer and the cprb buffer.\n\nOverall this cleans the internal used buffer in case of clear key\nimport to prevent sensitive data to get exposed.",
