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。

  - Linux カーネルでは、以下の脆弱性が解決されています: KEYS: trusted: Fix memory leak on object td Two error return paths are neglecting to free allocated object td, causing a memory leak. Fix this by returning via the error return path that securely kfree's td. Fixes clang scan-build warning:
    security/keys/trusted-keys/trusted_tpm1.c:496:10: warning: Potential memory leak [unix.Malloc] (CVE-2021-47009)

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。

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-986728 advisory.

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

    KEYS: trusted: Fix memory leak on object td

    Two error return paths are neglecting to free allocated object td,     causing a memory leak. Fix this by returning via the error return     path that securely kfree's td.

    Fixes clang scan-build warning:
    security/keys/trusted-keys/trusted_tpm1.c:496:10: warning: Potential     memory leak [unix.Malloc]

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.
