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。

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.

  - cpufreq: intel_pstate: Fix crash during turbo disable When the system is booted with kernel command line     argument nosmt or maxcpus to limit the number of CPUs, disabling turbo via: echo 1 >     /sys/devices/system/cpu/intel_pstate/no_turbo results in a crash: PF: supervisor read access in kernel     mode PF: error_code(0x0000) - not-present page PGD 0 P4D 0 Oops: Oops: 0000 [#1] SMP PTI ... RIP:
    0010:store_no_turbo+0x100/0x1f0 ... This occurs because for_each_possible_cpu() returns CPUs even if they     are not online. For those CPUs, all_cpu_data[] will be NULL. Since commit 973207ae3d7c (cpufreq:
    intel_pstate: Rearrange max frequency updates handling code), all_cpu_data[] is dereferenced even for     CPUs which are not online, causing the NULL pointer dereference. To fix that, pass CPU number to     intel_pstate_update_max_freq() and use all_cpu_data[] for those CPUs for which there is a valid cpufreq     policy. (CVE-2026-23332)

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