CVE-2024-50218
ocfs2: pass u64 to ocfs2_truncate_inline maybe overflow
In the Linux kernel, the following vulnerability has been resolved:
ocfs2: pass u64 to ocfs2_truncate_inline maybe overflow
Syzbot reported a kernel BUG in ocfs2_truncate_inline. There are two
reasons for this: first, the parameter value passed is greater than
ocfs2_max_inline_data_with_xattr, second, the start and end parameters of
ocfs2_truncate_inline are "unsigned int".
So, we need to add a sanity check for byte_start and byte_len right before
ocfs2_truncate_inline() in ocfs2_remove_inode_range(), if they are greater
than ocfs2_max_inline_data_with_xattr return -EINVAL.
