 漏洞简述：
  In the Linux kernel, the following vulnerability has been resolved:coresight: prevent deactivate active config while enabling the configWhile enable active config via cscfg_csdev_enable_active_config(),active config could be deactivated via configfs  sysfs interface.This could make UAF issue in below scenario:CPU0                                          CPU1(sysfs enable)                                load module                                              cscfg_load_config_sets()                                              activate config. // sysfs                                              (sys_active_cnt == 1)...cscfg_csdev_enable_active_config()lock(csdev->cscfg_csdev_lock)// here load config activate by CPU1unlock(csdev->cscfg_csdev_lock)                                              deactivate config // sysfs                                              (sys_activec_cnt == 0)                                              cscfg_unload_config_sets()                                              unload module// access to config_desc which freed// while unloading module.cscfg_csdev_enable_configTo address this, use cscfg_config_desc s active_cnt as a reference count which will be holded when    - activate the config.    - enable the activated config.and put the module reference when config_active_cnt == 0.
