- Summary
- KVM: arm64: Take the SRCU lock for page table walks in fault injection and AT emulation
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: Take the SRCU lock for page table walks in fault injection and AT emulation
walks1() and kvmwalknesteds2() expect to be called while holding kvm->srcu to guard against memslot changes. While this is generally the case, __kvmats12() and __kvmfinds1desclevel() call into the respective walkers without taking kvm->srcu.
Fix by acquiring kvm->srcu prior to the table walk in both instances.
