If\nuser-space provides a short buffer, meaning a larger report->length than\nthe actually written payload, up to around 4K of kernel data from past\nthe kmalloc(len + 1) sized buffer allocated in kernfs_fop_write_iter()\nwill leak into the SCLP report.\n\nHowever, as the entity processing the SCLP is privileged and able to\naccess at least the page including the report, this does not leak data\nthat entity could not access but it is still an out of bounds read and\na malformed error report that should be rejected."
