      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nKVM: arm64: vgic-its: Reject restored DTE with out-of-range num_eventid_bits\n\nUserspace can restore an ITS Device Table Entry whose Size field encodes\nmore EventID bits than the virtual ITS supports.  The live MAPD path\nrejects that state, but vgic_its_restore_dte() accepts it and stores the\nout-of-range value in dev->num_eventid_bits.\n\nReject restored DTEs with num_eventid_bits > VITS_TYPER_IDBITS before\nallocating the device.  This mirrors the MAPD check and prevents the\nrestored state from reaching vgic_its_restore_itt(), where the unchecked\nvalue can be converted into an oversized scan_its_table() range.",
