In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Fix uninitialized memcache pointer in user_mem_abort() Commit fce886a60207 ("KVM: arm64: Plumb the pKVM MMU in KVM") made the initialization of the local memcache variable in user_mem_abort() conditional, leaving a codepath where it is used uninitialized via kvm_pgtable_stage2_map(). This can fail on any path that requires a stage-2 allocation without transition via a permission fault or dirty logging. Fix this by making sure that memcache is always valid.
