Subject: [Intel-wired-lan] [PATCH 0/5] Ensure the copied buf is NULL terminated
Date: Mon, 22 Apr 2024 23:41:35 +0700 [thread overview]
Message-ID: <20240422-fix-oob-read-v1-0-e02854c30174@gmail.com> (raw)
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 or allocating count + 1 buffer then writing the NULL
terminator to end of buffer after userspace copying.
Thanks,
Quang Minh.
