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

  - powerpc/hv-gpci: fix preempt count leak in sysfs show paths Four sysfs show() callbacks in hv-gpci take     get_cpu_var(hv_gpci_reqb) (which calls preempt_disable()) but only call the matching put_cpu_var() on the     error path under the 'out:' label. Every successful read leaks one preempt_disable():
    processor_bus_topology_show() processor_config_show() affinity_domain_via_virtual_processor_show()     affinity_domain_via_domain_show() (affinity_domain_via_partition_show() was already correct.) On a     CONFIG_PREEMPT=y kernel, repeated reads raise preempt_count and eventually return to userspace with     preemption still disabled. The next user-mode page fault then hits faulthandler_disabled() == 1, gets     forced to SIGSEGV, and the resulting coredump trips 'BUG: scheduling while atomic' in     call_usermodehelper_exec -> wait_for_completion_state -> schedule: BUG: scheduling while atomic:
    <task>/<pid>/0x00000004 ... __schedule_bug+0x6c/0x90 __schedule+0x58c/0x13a0 schedule+0x48/0x1a0     schedule_timeout+0x104/0x170 wait_for_completion_state+0x16c/0x330 call_usermodehelper_exec+0x254/0x2d0     vfs_coredump+0x1050/0x2590 get_signal+0xb9c/0xc80 do_notify_resume+0xf8/0x470 Add an out_success label     that calls put_cpu_var() before returning the byte count, mirroring affinity_domain_via_partition_show().
    (CVE-2026-64070)

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