Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> KVM: arm64: Take the SRCU lock for page table walks in fault injection and AT emulation<br /> <br /> walk_s1() and kvm_walk_nested_s2() expect to be called while holding<br /> kvm-&gt;srcu to guard against memslot changes. While this is generally<br /> the case, __kvm_at_s12() and __kvm_find_s1_desc_level() call into the<br /> respective walkers without taking kvm-&gt;srcu.<br /> <br /> Fix by acquiring kvm-&gt;srcu prior to the table walk in both instances.
