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。

  - powerpc/pseries： papr-phy-attest - 驗證 cmd.length，plug mem leak 在 papr_phy_attest_create_handle（） 中，params->cmd.length 在使用前不會經過驗證，這可能會導致緩衝區過低。檢查它並返回 -EINVAL 如果它是 0 或超過 sizeof（params->cmd）。此外，引數會在成功路徑上釋放，但不會釋放錯誤。記憶體配置後出錯時釋放它。並在負 fd 上釋放它。（CVE-2026-80571）

請注意，Nessus 的判定取決於廠商所報告的套件是否存在。

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。

  - powerpc/pseries：papr-phy-attest - 验证 cmd.length，插入内存泄漏 在 papr_phy_attest_create_handle（） 中，params->cmd.length 在使用前未经验证，可导致缓冲区溢出。请检查此项，如果为 0 或超过 sizeof（params->cmd），则返回 -EINVAL。此外，params 会在成功路径上释放，但不会释放错误。内存分配后出错时将其释放。并在负 fd 上释放它。（CVE-2026-80571）

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。

  - powerpc/pseries:papr-phy-attest - cmd.length を検証し、メモリ漏洩をプラグします papr_phy_attest_create_handle() では、params->cmd.length が使用前に検証されません。これにより、バッファオーバーフローが発生する可能性があります。これをチェックし、0 であるか sizeof(params->cmd) を超えている場合は -EINVAL を返します。また、paramsは成功パスで解放されますが、エラーは解放されません。メモリ割り当て後のエラーでこれを解放します。そして、負の fd でそれを解放します。(CVE-2026-80571)

Nessus は、ベンダーから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。

The remote Oracle Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2026-95370 advisory.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux 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.

  - In the Linux kernel, the following vulnerability has been resolved: powerpc/pseries: papr-phy-attest -     validate cmd.length, plug mem leak In papr_phy_attest_create_handle(), the params->cmd.length is not     validated before use, which can result in a buffer overlow. Check it and return -EINVAL if it is either 0     or exceeds sizeof(params->cmd). Also, params is freed on the success path but not error. Free it on errors     after memory allocation. And free it on negative fd. (CVE-2026-80571)

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