The vulnerabilities of the functions trace_string() and trace_event_rawevent_synth() in the kernel/trace/trace_events_synth.c module, which support Linux’s kernel tracing mechanism, allow a hacker to cause a system failure.

The vulnerability of the tracestring and traceeventraweventsynth functions in the kernel/trace/traceeventssynth.c module, which support kernel tracing in Linux operating systems, is related to incorrect input validation. Exploiting this vulnerability could allow an attacker to cause a system...
