Official Description

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).

Technical Analysis

CVE-2026-46062 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation does not require any privileges, though user interaction (Required) is needed, which slightly reduces the risk of mass automated attacks.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 7.8.
