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。

  - netfilter： nf_nat：取消註冊並在錯誤時釋放鉤子 如果 nf_hook_entries_insert_raw（） 失敗，NAT 鉤子永遠不會釋放，從而導致 memleak。註冊掛勾時，延遲設定 nat_proto_net->nat_hook_ops，以簡化錯誤路徑，以決定 nat 掛勾是否需要解除處理。
    (CVE-2026-98321)

請注意，Nessus 依賴供應商報告的套件存在。

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。

  - netfilter：nf_nat：取消注册并在出错时释放挂钩 如果 nf_hook_entries_insert_raw（） 失败，则永远不会释放 NAT 挂钩，从而导致内存泄漏。注册挂钩时推迟设置 nat_proto_net->nat_hook_ops，以简化错误路径来确定 NAT 挂钩是否需要展开。
    (CVE-2026-98321)

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。

  - netfilter:nf_nat:エラー時にフックを登録解除してリリースします。nf_hook_entries_insert_raw() が失敗すると、NAT フックは決して解放されないため、メモリ漏洩が発生します。フックが登録されるときに設定 nat_proto_net->nat_hook_ops を延期して、エラー パスを簡略化して、nat フックを巻き戻す必要があるかどうかを判断します。
    (CVE-2026-98321)

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.

  - netfilter: nf_nat: unregister and release hooks on error If nf_hook_entries_insert_raw() fails, the NAT     hooks get never released, resulting in a memleak. Postpone setting nat_proto_net->nat_hook_ops when the     hooks are registered to simplify the error path to decide whether the nat hooks need unwinding.
    (CVE-2026-98321)

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

The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1793786843 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: soc: qcom: qmi_encdec: Restrict string     length in decode The QMI TLV value for strings in a lot of qmi element info structures account for null     terminated strings with MAX_LEN + 1. If a string is actually MAX_LEN + 1 length, this will cause an out of     bounds access when the NULL character is appended in decoding. (CVE-2023-53729)

  - In the Linux kernel, the following vulnerability has been resolved: rv: Use strings in da monitors     tracepoints Using DA monitors tracepoints with KASAN enabled triggers the following warning: BUG: KASAN:
    global-out-of-bounds in do_trace_event_raw_event_event_da_monitor+0xd6/0x1a0 Read of size 32 at addr     ffffffffaada8980 by task ... Call Trace: <TASK> [...] do_trace_event_raw_event_event_da_monitor+0xd6/0x1a0     ? __pfx_do_trace_event_raw_event_event_da_monitor+0x10/0x10 ? trace_event_sncid+0x83/0x200     trace_event_sncid+0x163/0x200 [...] The buggy address belongs to the variable: automaton_snep+0x4e0/0x5e0     This is caused by the tracepoints reading 32 bytes __array instead of __string from the automata     definition. Such strings are literals and reading 32 bytes ends up in out of bound memory accesses (e.g.
    the next automaton's data in this case). The error is harmless as, while printing the string, we stop at     the null terminator, but it should still be fixed. Use the __string facilities while defining the     tracepoints to avoid reading out of bound memory. (CVE-2025-38636)

  - In the Linux kernel, the following vulnerability has been resolved: perf: arm_spe: Prevent overflow in     PERF_IDX2OFF() Cast nr_pages to unsigned long to avoid overflow when handling large AUX buffer sizes (>= 2     GiB). (CVE-2025-40081)

  - In the Linux kernel, the following vulnerability has been resolved: arch_topology: Fix incorrect error     check in topology_parse_cpu_capacity() Fix incorrect use of PTR_ERR_OR_ZERO() in     topology_parse_cpu_capacity() which causes the code to proceed with NULL clock pointers. The current logic     uses !PTR_ERR_OR_ZERO(cpu_clk) which evaluates to true for both valid pointers and NULL, leading to     potential NULL pointer dereference in clk_get_rate(). Per include/linux/err.h documentation,     PTR_ERR_OR_ZERO(ptr) returns: The error code within @ptr if it is an error pointer; 0 otherwise. This     means PTR_ERR_OR_ZERO() returns 0 for both valid pointers AND NULL pointers. Therefore     !PTR_ERR_OR_ZERO(cpu_clk) evaluates to true (proceed) when cpu_clk is either valid or NULL, causing     clk_get_rate(NULL) to be called when of_clk_get() returns NULL. Replace with !IS_ERR_OR_NULL(cpu_clk)     which only proceeds for valid pointers, preventing potential NULL pointer dereference in clk_get_rate().
    (CVE-2025-40346)

  - In the Linux kernel, the following vulnerability has been resolved: platform/x86/amd/pmc: Add support for     Van Gogh SoC The ROG Xbox Ally (non-X) SoC features a similar architecture to the Steam Deck. While the     Steam Deck supports S3 (s2idle causes a crash), this support was dropped by the Xbox Ally which only S0ix     suspend. Since the handler is missing here, this causes the device to not suspend and the AMD GPU driver     to crash while trying to resume afterwards due to a power hang. (CVE-2025-68334)

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