An update of the linux package has been released.

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

  - smb: client: reject overlapping data areas in SMB2 responses Commit 53b7c271f06b (smb: client: restrict     implied bcc[0] exemption to responses without data area) restricted the implied bcc[0] length exception     to responses without a data area. However, the overlap handling in __smb2_calc_size() clears data_length,     which can make an invalid response appear to have no data area and so qualify for the exception. Track     data area overlap separately and reject such responses before applying the length compatibility     exceptions. (CVE-2026-64257)

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

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-131721 advisory.

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

    smb: client: reject overlapping data areas in SMB2 responses

    Commit 53b7c271f06b (smb: client: restrict implied bcc[0] exemption to     responses without data area) restricted the implied bcc[0] length     exception to responses without a data area. However, the overlap     handling in __smb2_calc_size() clears data_length, which can make an     invalid response appear to have no data area and so qualify for the     exception.

    Track data area overlap separately and reject such responses before     applying the length compatibility exceptions.

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

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