KVM: arm64: Correctly cap TLBI Range to the architural limit<\/p>\n
TLB Invalidation by Range has a fairly powerful way of encoding pretty
\nlarge ranges in a small number of bits. This range can be based on an
\narbitrary VA, which means it is pretty easy for a guest to generate an
\noverflow should the hypervisor be naive enough to add the range to the
\nbase…<\/p>\n
Make sure the range is capped to the limit dictated by the address bit
\nthat determines the VA range. For an IPA invalidation, this is further
\ncorrected down the line to ignore the upper range.<\/p>\n","protected":false},"excerpt":{"rendered":"
