Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。

  - 已修复 Linux 内核中的下列漏洞：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)

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。
