      "value": "An issue was discovered in the Linux kernel through 4.17.2. 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 an\u00e1lisis del filtros en kernel/trace/trace_events_filter.c podr\u00eda ser llamado sin un filtro, que es un caso N=0 cuando espera que, por lo menos, se haya le\u00eddo una l\u00ednea, lo que hace que el \u00edndice N-1 no sea v\u00e1lido. Esto permite que los atacantes provoquen una denegaci\u00f3n de servicio (escritura fuera de l\u00edmites del slab) u otro tipo de impacto mediante llamadas del sistema perf_event_open y mmap."
