  - 已解決 Linux 核心中的下列弱點：media: dvb-frontends: fix leak of memory fw (CVE-2022-50664)

  - 已解決 Linux 核心中的下列弱點：acct: fix potential integer overflow in encode_comp_t() The integer overflow is descripted with following codes: > 317 static comp_t encode_comp_t(u64 value) > 318 { > 319 int exp, rnd; ...... > 341 exp <<= MANTSIZE; > 342 exp += value; > 343 return exp; > 344 } Currently comp_t is defined as type of '__u16', but the variable 'exp' is type of 'int', so overflow would happen when variable 'exp' in line 343 is greater than 65535. (CVE-2022-50749)

  - 已解決 Linux 核心中的下列弱點：ext2: Add sanity checks for group and filesystem size Add sanity check that filesystem size does not exceed the underlying device size and that group size is big enough so that metadata can fit into it. This avoid trying to mount some crafted filesystems with extremely large group counts. (CVE-2022-50815)

請注意，Nessus 並未測試這些問題，而是僅依據應用程式自我報告的版本號碼作出判斷。

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

  - ext2新增群組和檔案系統大小的功能健全檢查新增功能健全檢查檢查檔案系統大小不會超過基礎裝置大小且群組大小是否夠大以便詮釋資料可以放進去。這可避免嘗試掛載某些具有極大群組計數的特製檔案系統。 (CVE-2022-50815)

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。

  - ext2为组和文件系统大小添加健全性检查 添加健全性检查文件系统大小不会超过底层设备大小并且组大小足够大以便元数据可以放入其中。这可避免尝试挂载某些具有极大群组计数的特制文件系统。 (CVE-2022-50815)

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。

Nessus はこれらの問題をテストしておらず、代わりにアプリケーションが自己報告するバージョン番号にのみ依存していることに注意してください。

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。

  - ext2グループおよびファイルシステムサイズのサニティチェックを追加します。ファイルシステムサイズが下層のデバイスサイズを超えないこと、およびグループサイズがメタデータが収まるのに十分なサイズであることを悪用して、サニティチェックを追加します。これにより、非常に大きなグループカウントで細工されたファイルシステムのマウントを回避できます。CVE-2022-50815

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 Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - ext2: Add sanity checks for group and filesystem size Add sanity check that filesystem size does not     exceed the underlying device size and that group size is big enough so that metadata can fit into it. This     avoid trying to mount some crafted filesystems with extremely large group counts. (CVE-2022-50815)

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

The CentOS Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS6:CLSA-2026:1792245431 advisory.
