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.
