In the Linux kernel, the following vulnerability has been resolved:
ocfs2: pass u64 to ocfs2truncateinline maybe overflow
Syzbot reported a kernel BUG in ocfs2truncateinline. There are two reasons for this: first, the parameter value passed is greater than ocfs2maxinlinedatawithxattr, second, the start and end parameters of ocfs2truncate_inline are "unsigned int".
So, we need to add a sanity check for bytestart and bytelen right before ocfs2truncateinline() in ocfs2removeinoderange(), if they are greater than ocfs2maxinlinedatawithxattr return -EINVAL.
