  "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-\u003eactive_cnt. Fix this by properly calling cscfg_csdev_disable_active_config() in these error paths.",
