         - CVE-2025-22839: Insufficient granularity of access control in the OOB-MSM for some Intel Xeon 6     Scalable processors may allow a privileged user to potentially enable escalation of privilege via adjacent     access.
         - CVE-2025-22889: Improper handling of overlap between protected memory ranges for some Intel Xeon 6     processor with Intel TDX may allow a privileged user to potentially enable escalation of privilege via     local access.
         - CVE-2025-20053: Improper buffer restrictions for some Intel Xeon Processor firmware with SGX     enabled may allow a privileged user to potentially enable escalation of privilege via local access.
         - CVE-2025-26403: Out-of-bounds write in the memory subsystem for some Intel Xeon 6 processors when     using Intel SGX or Intel TDX may allow a privileged user to potentially enable escalation of privilege via     local access.
         - CVE-2025-32086: Improperly implemented security check for standard in the DDRIO configuration for     some Intel Xeon 6 Processors when using Intel SGX or Intel TDX may allow a privileged user to potentially     enable escalation of privilege via local access.

      New Disclosures Updated in Prior Releases:
      All ADL, RPL, SPR, EMR, MTL, ARL Microcode patches previously released in May 2025.

Tenable has extracted the preceding description block directly from the SUSE 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.

  - Insufficient granularity of access control in the OOB-MSM for some Intel(R) Xeon(R) 6 Scalable processors     may allow a privileged user to potentially enable escalation of privilege via adjacent access.
    (CVE-2025-22839)

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

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。

  - 部分 Intel(R) Xeon(R) 6 可扩展处理器的 OOB-MSM 中的访问控制粒度不足可能允许特权用户通过邻近访问启用权限提升。
    (CVE-2025-22839)

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。

Linux/Unix ホストには、ベンダーが提供するパッチが利用できない脆弱性の影響を受ける複数のパッケージがインストールされています。

  - 一部の Intel(R) Xeon(R) 6 スケーラブルプロセッサ用の OOB-MSM におけるアクセスコントロールの粒度が不十分なため、特権ユーザーが隣接アクセスを通じて権限を昇格させる可能性があります。
    (CVE-2025-22839)

Nessus は、ベンダーによって報告されたパッケージの存在に依存していることに注意してください。

Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且廠商未提供可用的修補程式。

  - OOB-MSM 中某些 Intel(R) Xeon(R) 6 Scalable 處理器的存取控制細微度不足可能導致有權限的使用者透過相鄰存取權提升權限。
    (CVE-2025-22839)

請注意，Nessus 依賴供應商報告的套件存在。
