Description

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