  "details": "In the Linux kernel, the following vulnerability has been resolved:  KVM: arm64: vgic-its: Reject restored DTE with out-of-range num_eventid_bits  Userspace can restore an ITS Device Table Entry whose Size field encodes more EventID bits than the virtual ITS supports.  The live MAPD path rejects that state, but vgic_its_restore_dte() accepts it and stores the out-of-range value in dev-\u003enum_eventid_bits.  Reject restored DTEs with num_eventid_bits \u003e VITS_TYPER_IDBITS before allocating the device.  This mirrors the MAPD check and prevents the restored state from reaching vgic_its_restore_itt(), where the unchecked value can be converted into an oversized scan_its_table() range.",
