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。

  - canj1939NETDEV_UNREGISTER 通知ハンドラーを実装 syzbot は unregister_netdevice を報告します
    vcan0 が解放されるまで待機します。使用率 = 2 の問題は、j1939 プロトコル用には、j1939_sk_bind() によって行われた変更を取り消すための NETDEV_UNREGISTER 通知ハンドラーがありませんでした。コミット25fe97cb7620canj1939j1939_priv_put()をsk_destruct callbackに移動は、j1939_priv_put()への呼び出しが、j1939_sk_sock_destruct()が呼び出されるまで無条件で遅延する可能性があることを想定しています。しかし、NETDEV_UNREGISTER 通知が起動されるとすぐに、すなわち j1939_sk_sock_destruct() が j1939_sk_release() を介して呼び出される前に、j1939_sk_bind() の呼び出しによって保持される追加の ref に対して j1939_priv_put() を呼び出す必要がありますj1939_sk_bind() によって行われる変更の取り消しの一部として。または、j1939_sk_bind() 呼び出しによって保持される struct j1939_priv での追加の参照により、struct net_device は使用率カウントを 1 にドロップしません。 unregister_netdevice() を続行できなくなります。 [mklラベルの前のスペースを削除します]CVE-2025-39925

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.

  - can: j1939: implement NETDEV_UNREGISTER notification handler syzbot is reporting unregister_netdevice:
    waiting for vcan0 to become free. Usage count = 2 problem, for j1939 protocol did not have     NETDEV_UNREGISTER notification handler for undoing changes made by j1939_sk_bind(). Commit 25fe97cb7620     (can: j1939: move j1939_priv_put() into sk_destruct callback) expects that a call to j1939_priv_put()     can be unconditionally delayed until j1939_sk_sock_destruct() is called. But we need to call     j1939_priv_put() against an extra ref held by j1939_sk_bind() call (as a part of undoing changes made by     j1939_sk_bind()) as soon as NETDEV_UNREGISTER notification fires (i.e. before j1939_sk_sock_destruct() is     called via j1939_sk_release()). Otherwise, the extra ref on struct j1939_priv held by j1939_sk_bind()     call prevents struct net_device from dropping the usage count to 1; making it impossible for     unregister_netdevice() to continue.

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

The remote openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2025:03634-1 advisory.
