A fix is available — apply it.

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

ntfs3: fix integer overflow in run_unpack() volume boundary check

The volume boundary check lcn + len > sbi->used.bitmap.nbits uses raw addition which can wrap around for large lcn and len values, bypassing the validation. Use check_add_overflow() as is already done for the adjacent prev_lcn + dlcn and vcn64 + len checks added by commit 3ac37e100385 ("ntfs3: Fix integer overflow in run_unpack()").

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