Vulnerability details

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a use-after-free error within the apply_event_filter() function in kernel/trace/trace_events_filter.c, within the remove_subsystem(), event_enable_read(), event_enable_write(), event_filter_read() and trace_create_new_event() functions in kernel/trace/trace_events.c, within the register_event_command() function in kernel/trace/trace.h, within the tracing_open_file_tr() and tracing_release_file_tr() functions in kernel/trace/trace.c. A local user can escalate privileges on the system.
