-Subject: [PATCH 2/9] CVE-2019-13104: ext4: check for underflow in
- ext4fs_read_file
-
-in ext4fs_read_file, it is possible for a broken/malicious file
-system to cause a memcpy of a negative number of bytes, which
-overflows all memory. This patch fixes the issue by checking for
-a negative length.
