Vulnerability in Linux

[ Description ]Official description

In the Linux kernel, the following vulnerability has been resolved: ntfs: treat any nonzero dio zero-range return as an error ntfs_dio_zero_range() returns either 0 or a negative errno from blkdev_issue_zeroout(); it never returns a positive value. The zeroing failure check in ntfs_attr_fallocate() therefore never fired, so a failed zeroing operation was silently ignored: the loop kept going, the newly allocated clusters were folded into initialized_size and the write could succeed leaving stale on-disk data. Treat any nonzero return as an error and abort the allocation.
