      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nKVM: TDX: Reject concurrent change to CPUID entry count\n\nReject KVM_TDX_INIT_VM if userspace changes cpuid.nent between the\ninitial read and the subsequent copy of the initialization data.\n\ntdx_td_init() first reads user_data->cpuid.nent to size the flexible\nkvm_tdx_init_vm copy.  The copied structure also contains cpuid.nent,\nand that field can differ from the value used to size the allocation if\nuserspace modifies the input concurrently.  setup_tdparams_cpuids() later\npasses init_vm->cpuid.nent to kvm_find_cpuid_entry2(), which uses it as\nthe array bound for the copied entries.\n\nRequire the copied count to match the value used to size the allocation\nso that CPUID parsing cannot access beyond the entries actually copied.",
