Title
fs/ntfs3: Validate buffer length while parsing index
Summary
In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Validate buffer length while parsing index indx_read is called when we have some NTFS directory operations that need more information from the index buffers. This adds a sanity check to make sure the returned index buffer length is legit, or we may have some out-of-bound memory accesses.
