  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nPM / devfreq: Fix buffer overflow in trans_stat_show\n\nFix buffer overflow in trans_stat_show().\n\nConvert simple snprintf to the more secure scnprintf with size of\nPAGE_SIZE.\n\nAdd condition checking if we are exceeding PAGE_SIZE and exit early from\nloop. Also add at the end a warning that we exceeded PAGE_SIZE and that\nstats is disabled.\n\nReturn -EFBIG in the case where we don't have enough space to write the\nfull transition table.\n\nAlso document in the ABI that this function can return -EFBIG error.",
