Summary
In the Linux kernel, the following vulnerability has been resolved: ila: do not generate empty messages in ila_xlat_nl_cmd_get_mapping() ila_xlat_nl_cmd_get_mapping() generates an empty skb, triggerring a recent sanity check [1]. Instead, return an error code, so that user space can get it.
