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。

  - vsock/virtio：僅帳戶 read_skb（） 中的未讀取位元組 在接收部分資料流後，rx_bytes 會追蹤未讀取後綴，而buf_used和對等點仍會覆蓋整個封包。virtio_transport_read_skb（） 會出列該封包，但會傳遞兩個計數器的pkt_len，從而使rx_bytes下溢。在具有 SK_SKB 判定的已連接 CID_LOCAL 流上，從 100 位元組封包讀取 40 位元組使 SIOCINQ 報告 -40、空 recv 傳回 ELOOP，並輪詢報告空通訊端可讀。在判定分離之後，接收 40 個位元組會將計數器包裝為零，並隱藏那些排入佇列的位元組，直到另一個位元組到達為止。修正執行可保持計數器平衡，並立即公開所有佇列資料。這是在對 VSOCK 接收會計進行 LLM 輔助手動來源稽核時發現的，同時重新評估之後的 virtio_transport_read_skb（）。CVE-2024-50169 僅從 rx_bytes 減去 skb->len 減去 VSOCK 位移。保留buf_used和對等積分的完整封包長度。（CVE-2026-99062）

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。

  - vsock/virtio：仅考虑 read_skb（） 中的未读字节 在部分流接收后，rx_bytes 会在 buf_used 和对等机信用仍然覆盖整个数据包时跟踪未读后缀。virtio_transport_read_skb（） 会将该数据包出列，但同时针对两个计数器传递pkt_len，从而导致下溢rx_bytes。在具有 SK_SKB 判定的连接的 CID_LOCAL 流上，从 100 字节数据包中读取 40 字节使 SIOCINQ 报告 -40，空 recv 返回 ELOOP，并使轮询报告空套接字可读。在判定分离之后，接收 40 个字节会将计数器封装为零并隐藏这些已排入队列的字节，直到再有一个字节到达为止。固定运行可保持计数器平衡并立即暴露所有排队数据。这是在 后重新评估 virtio_transport_read_skb（） CVE-2024-50169时对 VSOCK 接收记账进行 LLM 协助的手动源审计期间发现的。仅从 rx_bytes 减去 skb->len 减去 VSOCK 偏移。为buf_used和对等机信用保留完整的数据包长度。（CVE-2026-99062）

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。

  - vsock/virtio:read_skb() の未読バイトのみをアカウントします。部分的なストリームの受信後、rx_bytes は未読サフィックスを追跡しますが、buf_used とピアのクレジットは依然としてパケット全体をカバーします。virtio_transport_read_skb() はそのパケットをキューから外しますが、両方のカウンターにpkt_lenを渡して、rx_bytesをアンダーフローします。SK_SKB判定を持つ接続されたCID_LOCALストリームで、100バイトのパケットから40バイトの読み取りにより、SIOCINQは-40、空のrecvはELOOPを返し、ポーリングレポートは空のソケットを読み取り可能にしました。判定デタッチの後、40バイトを受信すると、カウンターがゼロにラップされ、もう1バイト到着するまでキューに入れられたバイトが非表示になります。修正済み実行では、カウンターのバランスが保たれ、キューに入れられたすべてのデータがただちに漏洩されました。これは、 CVE-2024-50169後にvirtio_transport_read_skb()を再評価しているときに、VSOCK受信アカウンティングのLLM支援による手動ソース監査中に発見されました。skb->len から rx_bytes から VSOCK オフセットを引いたもののみを減算します。buf_usedとピアのクレジットのためにパケットの全長を保持します。(CVE-2026-99062)

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: vsock/virtio: account only unread     bytes in read_skb() After a partial stream receive, rx_bytes tracks the unread suffix while buf_used and     peer credit still cover the whole packet. virtio_transport_read_skb() dequeues that packet but passes     pkt_len for both counters, underflowing rx_bytes. On a connected CID_LOCAL stream with an SK_SKB verdict,     a 40-byte read from a 100-byte packet made SIOCINQ report -40, an empty recv return ELOOP, and poll report     the empty socket readable. After verdict detach, receiving 40 bytes wrapped the counter to zero and hid     those queued bytes until one more byte arrived. The fixed run kept the counter balanced and exposed all     queued data immediately. This was found during an LLM-assisted manual source audit of VSOCK receive     accounting while re-evaluating virtio_transport_read_skb() after CVE-2024-50169. Subtract only skb->len     minus the VSOCK offset from rx_bytes. Retain the full packet length for buf_used and peer credit.
    (CVE-2026-99062)

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

An update of the linux package has been released.
