Vulnerability Title
fs/ntfs3: Return error for inconsistent extended attributes
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Return error for inconsistent extended attributes ntfs_read_ea is called when we want to read extended attributes. There are some sanity checks for the validity of the EAs. However, it fails to return a proper error code for the inconsistent attributes, which might lead to unpredicted memory accesses after return.
