    Package        : ntfs-3g     CVE ID         : CVE-2026-40706

    Andrea Bocchetti discovered a heap-based buffer overflow in NTFS-3G, a     read-write NTFS driver for FUSE. A local user can take advantage of this     flaw for local root privilege escalation.

    For the oldstable distribution (bookworm), this problem has been fixed     in version 1:2022.10.3-1+deb12u3.

    For the stable distribution (trixie), this problem has been fixed in     version 1:2022.10.3-5+deb13u1.

    We recommend that you upgrade your ntfs-3g packages.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The version of CBL-Mariner Releases installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2026-40706 advisory.

  - In NTFS-3G 2022.10.3 before 2026.2.25, a heap buffer overflow exists in ntfs_build_permissions_posix() in     acls.c that allows an attacker to corrupt heap memory in the SUID-root ntfs-3g binary by crafting a     malicious NTFS image. The overflow is triggered on the READ path (stat, readdir, open) when processing a     security descriptor with multiple ACCESS_DENIED ACEs containing WRITE_OWNER from distinct group SIDs.
