A valid length cannot yield a zero size, so the !sve_state_size test goes with it.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>KVM: arm64: Validate the SVE vector length in pkvm_vcpu_init_sve()</p> <p>pkvm_vcpu_init_sve() clamps only the upper bound of the host-provided sve_max_vl, so an invalid vector length reaches sve_state_size_from_vl() and the WARN_ON() there, which is fatal at EL2.
