CVE-2026-68283

The CVE-2026-68283 issue is in the Linux kernel tracing subsystem. A use-after-free arises because freeing of event_trigger_data was moved to a kthread and synchronized later via tracepoint_synchronize_unregister(), breaking prior inline synchronization in trigger_data_free(). As a result, after ...
