Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> KVM: arm64: Eagerly init vgic dist/redist on vgic creation<br /> <br /> If vgic_allocate_private_irqs_locked() fails for any odd reason,<br /> we exit kvm_vgic_create() early, leaving dist-&gt;rd_regions uninitialised.<br /> <br /> kvm_vgic_dist_destroy() then comes along and walks into the weeds<br /> trying to free the RDs. Got to love this stuff.<br /> <br /> Solve it by moving all the static initialisation early, and make<br /> sure that if we fail halfway, we&amp;#39;re in a reasonable shape to<br /> perform the rest of the teardown. While at it, reset the vgic model<br /> on failure, just in case...
