In the Linux kernel, the following vulnerability has been resolved:

fs/ntfs3: Add overflow check for attribute size

The offset addition could overflow and pass the used size check given an attribute with very large size (e.g., 0xffffff7f) while parsing MFT attributes. This could lead to out-of-bound memory R/W if we try to access the next attribute derived by Add2Ptr(attr, asize)
