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

walk s1() and kvm walk nested s2() expect to be called while holding kvm->srcu to guard against memslot changes. While this is generally the case, kvm at s12() and kvm find s1 desc level() call into the respective walkers without taking kvm->srcu.

Fix by acquiring kvm->srcu prior to the table walk in both instances.
