The filter parsing in kernel/trace/trace_events_filter.c could be called with no filter, which is an N=0 case when it expected at least one line to have been read, thus making the N-1 index invalid. This allows attackers to cause a denial of service (slab out-of-bounds write) or possibly have unspecified other impact via crafted perf_event_open and mmap system calls."

El análisis del filtros en kernel/trace/trace_events_filter.c podría ser llamado sin un filtro, que es un caso N=0 cuando espera que, por lo menos, se haya leído una línea, lo que hace que el índice N-1 no sea válido. Esto permite que los atacantes provoquen una denegación de servicio (escritura fuera de límites del slab) u otro tipo de impacto mediante llamadas del sistema perf_event_open y mmap."
