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

  - net: dlink: handle copy_thresh allocation failure The driver did not handle failure of     `netdev_alloc_skb_ip_align()`. If the allocation failed, dereferencing `skb->protocol` could lead to a     NULL pointer dereference. This patch tries to allocate `skb`. If the allocation fails, it falls back to     the normal path. Tested-on: D-Link DGE-550T Rev-A3 (CVE-2025-40053)

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

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。

  - netdlinkcopy_thresh 割り当ての失敗を処理します ドライバーが「netdev_alloc_skb_ip_align()」の失敗を処理しませんでした。割り当てが失敗した場合、逆参照「skb->protocol」は NULL ポインターデリファレンスにつながる可能性があります。このパッチは「skb」を割り当てようとします。割り当てが失敗した場合は、通常のパスにフォールバックします。Tested-onD-Link DGE-550T Rev-A3CVE-2025-40053

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，且供應商未提供可用的修補程式。

  - netdlink處理 copy_thresh 配置失敗驅動程式並未處理「netdev_alloc_skb_ip_align()」失敗。如果配置失敗解除參照「skb->protocol」可導致 NULL 指標解除參照。此修補程式會嘗試配置「skb」。如果配置失敗，則會回復為正常路徑。經過測試D-Link DGE-550T Rev-A3 (CVE-2025-40053)

請注意，Nessus 的判定取決於廠商所報告的套件是否存在。

An update of the linux package has been released.

The remote Debian 12 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-6053 advisory.

    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    For the oldstable distribution (bookworm), these problems have been fixed     in version 6.1.158-1.

    We recommend that you upgrade your linux packages.

    For the detailed security status of linux please refer to its security     tracker page at:

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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。

  - netdlink处理 copy_thresh 分配失败 驱动程序未处理 `netdev_alloc_skb_ip_align()` 的失败。如果分配失败则取消引用“skb->protocol”可导致空指针取消引用。此修补程序尝试分配“skb”。如果分配失败，系统会回退到正常路径。已在D-Link DGE-550T Rev-A3 上进行测试 (CVE-2025-40053)

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。
