📋 Description

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.
