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

  - KVM: arm64: Handle VNCR TLB invalidation race with vcpu_put() VNCR unmapping While VNCR TLB invalidation     always occurs under the MMU lock, vcpu_put() doesn't, while it unmaps the VNCR page. The problem is that     the invalidation evaluates vncr_tlb::cpu to decide whether an unmapping needs to take place (cpu != -1)     before performing it. On the other hand, this_cpu_reset_vncr_fixmap() unconditionally unmaps if     L1_VNCR_MAPPED is set. These two obviously can race, with a TOCTOU pattern on the TLBI path, and a     BUG_ON() on the vcpu_put() path. And the two can end-up calling vncr_fixmap(-1), with extra lethal     effects. Move the reset of vncr_tlb::cpu to -1 to a common function, and make this update atomic so that     only a single thread can reset the field and perform the corresponding unmap. The vcpu_put() still need to     unconditionally unmap the current VNCR to close another ugly race. Finally, the assignment of     vncr_tlb::cpu is moved to be kept in sync with the actual mapping, similar to L1_VNCR_MAPPED being set.
