遠端 CentOS Linux 9 主機已安裝受到多個弱點影響的套件如 kernel-5.14.0-648.el9 版本變更記錄中所提及。

  - 已解決 Linux 核心中的下列弱點：wifi: ath12k: Fix buffer overflow in debugfs If the user tries to write more than 32 bytes then it results in memory corruption. Fortunately, this is debugfs so it's limited to root users. (CVE-2025-38317)

  - 已解決 Linux 核心中的下列弱點：wifi: iwlwifi: mld: avoid panic on init failure In case of an error during init, in_hw_restart will be set, but it will never get cleared.
    Instead, we will retry to init again, and then we will act like we are in a restart when we are actually not. This causes (among others) to a NULL pointer dereference when canceling rx_omi::finished_work, that was not even initialized, because we thought that we are in hw_restart. Set in_hw_restart to true only if the fw is running, then we know that FW was loaded successfully and we are not going to the retry loop.
    (CVE-2025-38121)

  - 已解決 Linux 核心中的下列弱點：wifi: mt76: mt7915: Fix null-ptr-deref in mt7915_mmio_wed_init() devm_ioremap() returns NULL on error. Currently, mt7915_mmio_wed_init() does not check for this case, which results in a NULL pointer dereference. Prevent null pointer dereference in mt7915_mmio_wed_init(). (CVE-2025-38155)

  - 已解決 Linux 核心中的下列弱點：wifi: mt76: mt7996: Fix null-ptr-deref in mt7996_mmio_wed_init() devm_ioremap() returns NULL on error. Currently, mt7996_mmio_wed_init() does not check for this case, which results in a NULL pointer dereference. Prevent null pointer dereference in mt7996_mmio_wed_init() (CVE-2025-38156)

  - 已解決 Linux 核心中的下列弱點：wifi: ath9k_htc: Abort software beacon handling if disabled A malicious USB device can send a WMI_SWBA_EVENTID event from an ath9k_htc-managed device before beaconing has been enabled. This causes a device-by-zero error in the driver, leading to either a crash or an out of bounds read. Prevent this by aborting the handling in ath9k_htc_swba() if beacons are not enabled. (CVE-2025-38157)

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。

  - wifiiwlwifimld避免初始化失败中的错误如果初始化期间出错则将设置 in_hw_restart但永远不会清除。相反，我们会再次重试 init，然后就像处于重新启动中一样，但实际并非如此。这会造成 取消引用甚至没有初始化的 rx_omi::finished_work 时空指针取消引用因为我们认为正处于 hw_restart 中。仅当固件正在运行时将 in_hw_restart 设置为 true以便我们知道固件已成功加载并且我们不会进入重试循环。 (CVE-2025-38121)

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。

请注意，Nessus 尚未测试这些问题，而是只依据应用程序自我报告的版本号进行判断。

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。

  - wifi: iwlwifi: mld避免 init 失敗時發生錯誤。如果在 init 期間發生錯誤則 in_hw_restart 會被設定但絕不會遭到清除。相反我們會再次重試初始化然後我們會以重新啟動的方式進行而實際上並非如此。這在取消 rx_omi::finished_work 時會造成 (以及其他問題) NULL 指標解除參照甚至沒有初始化因為我們認為自己處於 hw_restart 中。只有在 fw 執行中時才將 in_hw_restart 設定為 true這樣我們就知道 FW 已成功載入且我們不會進入重試迴圈。 (CVE-2025-38121)

請注意，Nessus 依賴供應商報告的套件存在。

リモートの CentOS Linux 9 ホストには、kernel-5.14.0-648.el9 ビルド変更ログで言及されているように、複数の脆弱性の影響を受けるパッケージがインストールされています。

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。

  - wifiiwlwifimldinit 失敗時のパニックを回避します。init 中にエラーが発生した場合、in_hw_restart が設定されますが、決してクリアされません。代わりに init を再試行すると、実際には再起動していないときに再起動があるように動作します。これは他の問題とともに、rx_omi::finished_work をキャンセルする際に、NULL ポインターデリファレンスを引き起こします。これは、hw_restart 内であると考えられていたためです。fw が実行中の場合にのみ in_hw_restart を true に設定すると、FW が正常にロードされたことがわかり、再試行ループに陥ることがありません。CVE-2025-38121

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 remote CentOS Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the kernel-5.14.0-648.el9 build changelog.

  - In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: Fix buffer overflow in     debugfs If the user tries to write more than 32 bytes then it results in memory corruption. Fortunately,     this is debugfs so it's limited to root users. (CVE-2025-38317)

  - In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mld: avoid panic on     init failure In case of an error during init, in_hw_restart will be set, but it will never get cleared.
    Instead, we will retry to init again, and then we will act like we are in a restart when we are actually     not. This causes (among others) to a NULL pointer dereference when canceling rx_omi::finished_work, that     was not even initialized, because we thought that we are in hw_restart. Set in_hw_restart to true only if     the fw is running, then we know that FW was loaded successfully and we are not going to the retry loop.
    (CVE-2025-38121)

  - In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7915: Fix null-ptr-deref     in mt7915_mmio_wed_init() devm_ioremap() returns NULL on error. Currently, mt7915_mmio_wed_init() does not     check for this case, which results in a NULL pointer dereference. Prevent null pointer dereference in     mt7915_mmio_wed_init(). (CVE-2025-38155)

  - In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7996: Fix null-ptr-deref     in mt7996_mmio_wed_init() devm_ioremap() returns NULL on error. Currently, mt7996_mmio_wed_init() does not     check for this case, which results in a NULL pointer dereference. Prevent null pointer dereference in     mt7996_mmio_wed_init() (CVE-2025-38156)

  - In the Linux kernel, the following vulnerability has been resolved: wifi: ath9k_htc: Abort software beacon     handling if disabled A malicious USB device can send a WMI_SWBA_EVENTID event from an ath9k_htc-managed     device before beaconing has been enabled. This causes a device-by-zero error in the driver, leading to     either a crash or an out of bounds read. Prevent this by aborting the handling in ath9k_htc_swba() if     beacons are not enabled. (CVE-2025-38157)

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.

  - wifi: iwlwifi: mld: avoid panic on init failure In case of an error during init, in_hw_restart will be     set, but it will never get cleared. Instead, we will retry to init again, and then we will act like we are     in a restart when we are actually not. This causes (among others) to a NULL pointer dereference when     canceling rx_omi::finished_work, that was not even initialized, because we thought that we are in     hw_restart. Set in_hw_restart to true only if the fw is running, then we know that FW was loaded     successfully and we are not going to the retry loop. (CVE-2025-38121)

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