In the Linux kernel, the following vulnerability has been resolved: smb: client: validate the whole DACL before rewriting it in cifsacl build_sec_desc() and id_mode_to_cifs_acl() derive a DACL pointer from a server-supplied dacloffset and then use the incoming ACL to rebuild the chmod/chown security descriptor. The original fix only checked that the struct smb_acl header fits before reading dacl_ptr->size or dacl_ptr->num_aces. That avoids the immediate header-field OOB read, but the rewrite helpers still walk ACEs based on pdacl->num_aces with no structural validation of the incoming DACL body. A malicious server can return a truncated DACL that still contains a header, claims one or more ACEs, and then drive replace_sids_and_copy_aces() or set_chmod_dacl() past the validated extent while they compare or copy attacker-controlled ACEs. Factor the DACL structural checks into validate_dacl(), extend them to validate each ACE against the DACL bounds, and use the shared validator before the chmod/chown rebuild paths. parse_dacl() reuses the same validator so the read-side parser and write-side rewrite paths agree on what constitutes a well-formed incoming DACL.

The remote Debian 13 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-6253 advisory.

    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    For the stable distribution (trixie), these problems have been fixed in     version 6.12.86-1.

    We recommend that you upgrade your linux packages.

Tenable has extracted the preceding description block directly from the Debian security advisory.

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - smb: client: validate the whole DACL before rewriting it in cifsacl build_sec_desc() and     id_mode_to_cifs_acl() derive a DACL pointer from a server-supplied dacloffset and then use the incoming     ACL to rebuild the chmod/chown security descriptor. The original fix only checked that the struct smb_acl     header fits before reading dacl_ptr->size or dacl_ptr->num_aces. That avoids the immediate header-field     OOB read, but the rewrite helpers still walk ACEs based on pdacl->num_aces with no structural validation     of the incoming DACL body. A malicious server can return a truncated DACL that still contains a header,     claims one or more ACEs, and then drive replace_sids_and_copy_aces() or set_chmod_dacl() past the     validated extent while they compare or copy attacker-controlled ACEs. Factor the DACL structural checks     into validate_dacl(), extend them to validate each ACE against the DACL bounds, and use the shared     validator before the chmod/chown rebuild paths. parse_dacl() reuses the same validator so the read-side     parser and write-side rewrite paths agree on what constitutes a well-formed incoming DACL.
    (CVE-2026-31709)

Note that Nessus relies on the presence of the package as reported by the vendor.
