Summary
PM / devfreq: Fix buffer overflow in trans_stat_show
Details

In the Linux kernel, the following vulnerability has been resolved:

PM / devfreq: Fix buffer overflow in transstatshow

Fix buffer overflow in transstatshow().

Convert simple snprintf to the more secure scnprintf with size of PAGE_SIZE.

Add condition checking if we are exceeding PAGESIZE and exit early from loop. Also add at the end a warning that we exceeded PAGESIZE and that stats is disabled.

Return -EFBIG in the case where we don't have enough space to write the full transition table.

Also document in the ABI that this function can return -EFBIG error.
