Subject: [PATCH v2 0/6] Ensure the copied buf is NUL terminated
Hi everyone,
I found that some drivers contains an out-of-bound read pattern like this
kern_buf = memdup_user(user_buf, count);
...
sscanf(kern_buf, ...);
The sscanf can be replaced by some other string-related functions. This
pattern can lead to out-of-bound read of kern_buf in string-related
functions.
This series fix the above issue by replacing memdup_user with
memdup_user_nul.
Thanks,
Quang Minh.
