Then the driver tries to access\nfw_list.fw_names[i] with i >= ARRAY_SIZE and runs off the end\nof the array.\n\nFix this by initializing the fw_list and by not failing\ncompletely if the devcmd fails because other useful information\nis printed via devlink dev info even if the devcmd fails."}, {"lang": "es", "value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: pds_core: manejar resultados PDS_CORE_CMD_FW_CONTROL no compatibles.
