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

  - KVM: arm64: Fix pin leak and publication ordering in __pkvm_init_vcpu() Two bugs exist in the vCPU     initialisation path: 1. If a check fails after hyp_pin_shared_mem() succeeds, the cleanup path jumps to     'unlock' without calling unpin_host_vcpu() or unpin_host_sve_state(), permanently leaking pin references     on the host vCPU and SVE state pages. Extract a register_hyp_vcpu() helper that performs the checks and     the store. When register_hyp_vcpu() returns an error, call unpin_host_vcpu() and unpin_host_sve_state()     inline before falling through to the existing 'unlock' label. 2. register_hyp_vcpu() publishes the new     vCPU pointer into 'hyp_vm->vcpus[]' with a bare store, allowing a concurrent caller of     pkvm_load_hyp_vcpu() to observe a partially initialised vCPU object. Ensure the store uses     smp_store_release() and the load uses smp_load_acquire(). While 'vm_table_lock' currently serialises the     store and the load, these barriers ensure the reader sees the fully initialised 'hyp_vcpu' object even if     there were a lockless path or if the lock's own ordering guarantees were insufficient for nested object     initialization. (CVE-2026-46147)

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