Summary
coresight: etm4x: missing cscfg_csdev_disable_active_config() in perf enable
Details

In the Linux kernel, the following vulnerability has been resolved:

coresight: etm4x: missing cscfg_csdev_disable_active_config() in perf enable

In the perf enable path, there are missing cases where cscfg_csdev_disable_active_config() is not called:

  • Branch broadcast is selected but not supported by the hardware
  • etm4_enable_hw() fails

This can lead to a leak of config_desc->active_cnt. Fix this by properly calling cscfg_csdev_disable_active_config() in these error paths.
