NVD Description

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

ntfs3: add buffer boundary checks to run_unpack()

run_unpack() checks run_buf &lt; run_last at the top of the while loop but then reads size_size and offset_size bytes via run_unpack_s64() without verifying they fit within the remaining buffer. A crafted NTFS image with truncated run data in an MFT attribute triggers an OOB heap read of up to 15 bytes when the filesystem is mounted.

Add boundary checks before each run_unpack_s64() call to ensure the declared field size does not exceed the remaining buffer.

Found by fuzzing with a source-patched harness (LibAFL + QEMU).
