Summary
In the Linux kernel, the following vulnerability has been resolved: net: mvneta: Prevent out of bounds read in mvneta_config_rss() The pp->indir[0] value comes from the user. It is passed to: if (cpu_online(pp->rxq_def)) inside the mvneta_percpu_elect() function. It needs bounds checkeding to ensure that it is not beyond the end of the cpu bitmap.
