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。

  - ALSAhda清理轉碼器時不取消預先設定。ASoC 轉碼器驅動程式實作會重複使用參與轉碼器初始化和移除的數個函式。驅動程式會以 component->probe/remove() 模擬 sound/pci/hda/hda_bind.c 中所發現的 hda_codec_driver_probe/remove() 行為。其中一個原因是 snd_hda_codec_device_new() 預期會收到 struct snd_card 執行個體的有效指標。只有在音效卡元件開始探查後才能符合此預期。由於 ASoC 音效卡可能在未從系統實際移除轉碼器裝置的情況下解除系結因此取消設定 snd_hda_codec_cleanup_for_unbind() 中的 ->preset 會干擾模組卸載 -> 載入造成 null-ptr-deref 的狀況。預設只會在裝置/驅動程式比對期間指派一次而 ASoC 轉碼器驅動程式的模組重新載入可能會在音訊堆疊的整個存留期發生數次。

請注意，Nessus 依賴供應商報告的套件存在。

AlmaLinux 9.2 主機已安裝的套件會受到 TuxCare ALMALINUX9.2：CLSA-2026：1782151303 公告中提及的多個弱點影響。

  - 已解決 Linux 核心中的下列弱點：netfilter: ebtables: fix memory leak when blob is malformed The bug fix was incomplete, it replaced crash with a memory leak. The old code had an assignment to ret embedded into the conditional, restore this. (CVE-2022-48641)

  - 已解決 Linux 核心中的下列弱點：thermal/int340x_thermal: handle data_vault when the value is ZERO_SIZE_PTR In some case, the GDDV returns a package with a buffer which has zero length. It causes that kmemdup() returns ZERO_SIZE_PTR (0x10). Then the data_vault_read() got NULL point dereference problem when accessing the 0x10 value in data_vault. [ 71.024560] BUG: kernel NULL pointer dereference, address: 0000000000000010 This patch uses ZERO_OR_NULL_PTR() for checking ZERO_SIZE_PTR or NULL value in data_vault. (CVE-2022-48703)

  - 已解決 Linux 核心中的下列弱點：ice: switch: fix potential memleak in ice_add_adv_recipe() When ice_add_special_words() fails, the 'rm' is not released, which will lead to a memory leak. Fix this up by going to 'err_unroll' label. Compile tested only. (CVE-2022-48709)

  - 已解決 Linux 核心中的下列弱點：xen-netfront: Fix NULL sring after live migration A NAPI is setup for each network sring to poll data to kernel The sring with source host is destroyed before live migration and new sring with target host is setup after live migration. The NAPI for the old sring is not deleted until setup new sring with target host after migration. With busy_poll/busy_read enabled, the NAPI can be polled before got deleted when resume VM. BUG: unable to handle kernel NULL pointer dereference at 0000000000000008 IP: xennet_poll+0xae/0xd20 PGD 0 P4D 0 Oops:

  - 已解決 Linux 核心中的下列弱點：cifs: fix small mempool leak in SMB2_negotiate() In some cases of failure (dialect mismatches) in SMB2_negotiate(), after the request is sent, the checks would return -EIO when they should be rather setting rc = -EIO and jumping to neg_exit to free the response buffer from mempool. (CVE-2022-49938)

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。
