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。

  - thermal/drivers/cpufreq_cooling修复 slab OOB 问题 KASAN 在 cpu_power_to_freq() 中扫描 slab OOB 问题。如果将 EM 表中的功率限制在 OPP0 的功率以下将导致带有负数组索引的 slab 越界问题。如果有限功率无法在 EM 表中找到合适的 OPP则返回最低频率以修复此问题。Backtrace [<ffffffd02d2a37f0>] die+0x104/0x5ac [<ffffffd02d2a5630>] bug_handler+0x64/0xd0 [<ffffffd02d288ce4>] brk_handler+0x160/0x258 [<ffffffd02d281e5c>] do_debug_exception+0x248/0x3f0 [<ffffffd02d284488>] el1_dbg+0x14/0xbc [<ffffffd02d75d1d4>] __kasan_report+0x1dc/0x1e0 [<ffffffd02d75c2e0>] kasan_report+0x10/0x20 [<ffffffd02d75def8>] __asan_report_load8_noabort+0x18/0x28 [<ffffffd02e6fce5c>] cpufreq_power2state+0x180/0x43c [<ffffffd02e6ead80>] power_actor_set_power+0x114/0x1d4 [0xaec_power<ffffffd02e6fac24>] 0xde0 [<ffffffd02e6f9f80>] power_allocator_throttle+0x3ec/0x5a4 [<ffffffd02e6ea888>] handle_thermal_trip+0x160/0x294 [<ffffffd02e6edd08>] thermal_zone_device_check+0xe4/0x154 [<ffffffd02d351cb4>] process_one_work+0x5e4/0xe28 [<ffffffd02d352f44>] work_thread+0xa4c/0xfac [<ffffffd02d360124>] kthread+0x33c/0x358 [<ffffffd02d289940>] ret_from_fork+0xc/0x18 (CVE-2020-36776)

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - thermal/drivers/cpufreq_cooling: Fix slab OOB issue Slab OOB issue is scanned by KASAN in     cpu_power_to_freq(). If power is limited below the power of OPP0 in EM table, it will cause slab out-of-     bound issue with negative array index. Return the lowest frequency if limited power cannot found a     suitable OPP in EM table to fix this issue.
