CVE-2022-48848

CVE-2022-48848 affects the Linux kernel tracing/osnoise workflow. Concrete detail: the issue is caused by unregistering tracepoints twice when stopping tracing (osnoise_workload_stop) and switching tracer to nop, leading to a kernel warning about unregistering an unregistered tracepoint. The conn...
