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。

  - IIO：ADC：AD4030：修正無效的oversampling_ratio驗證 在 ad4030_set_avg_frame_len（） 中，對數是在輸入驗證之前計算的。傳遞零值或負值會導致 ilog2（） 產生未定義的結果。在計算輸入對數之前，先驗證輸入是否嚴格為正。（CVE-2026-98678）

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。

  - iio：adc：ad4030：修复无效的oversampling_ratio验证 在 ad4030_set_avg_frame_len（） 中，对数在输入验证之前计算。传递零值或负值会导致 ilog2（） 产生未定义的结果。在计算输入的对数之前，验证输入是否严格为正。（CVE-2026-98678）

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。

  - iio:adc:ad4030:無効なoversampling_ratio検証を修正します ad4030_set_avg_frame_len() では、入力検証の前に対数が計算されます。ゼロまたは負の値を渡すと、ilog2() から未定義の結果が生じます。対数を計算する前に、入力が厳密に正であることを検証します。(CVE-2026-98678)

Tenable has extracted the preceding description block directly from the Ubuntu 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: iio: adc: ad4030: fix invalid     oversampling_ratio validation In ad4030_set_avg_frame_len(), the logarithm is calculated before input     validation. Passing zero or negative values leads to an undefined result from ilog2(). Validate that the     input is strictly positive prior to computing its logarithm. (CVE-2026-98678)

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