See How to fix? for RHEL:8 relevant fixed versions and status.
In the Linux kernel, the following vulnerability has been resolved:
PM / devfreq: Fix buffer overflow in trans_stat_show
Fix buffer overflow in trans_stat_show().
Convert simple snprintf to the more secure scnprintf with size of PAGE_SIZE.
Add condition checking if we are exceeding PAGE_SIZE and exit early from loop. Also add at the end a warning that we exceeded PAGE_SIZE 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.
