- Summary
- KVM: arm64: nv: Inject SEA if kvm_translate_vncr() can't resolve PFN
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: nv: Inject SEA if kvmtranslatevncr() can't resolve PFN
kvmhandlevncrabort() assumes that s1walkresult conveys an abort when kvmtranslate_vncr() returns -EFAULT. This is not always the case as it's possible to encounter 'late' failures on the output of S1 translation, e.g. a GFN outside of the memslots.
Fix it by preparing an external abort before returning from kvmtranslatevncr(). Get rid of the BUG_ON() in the fault injection path while at it.
