- Summary
- KVM: arm64: vgic-its: Reject restored DTE with out-of-range num_eventid_bits
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: vgic-its: Reject restored DTE with out-of-range numeventidbits
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 vgicitsrestoredte() accepts it and stores the out-of-range value in dev->numeventid_bits.
Reject restored DTEs with numeventidbits > VITSTYPERIDBITS before allocating the device. This mirrors the MAPD check and prevents the restored state from reaching vgicitsrestoreitt(), where the unchecked value can be converted into an oversized scanits_table() range.
