Mô tả CVE
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.
