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.

CVE-2018-12714 kernel: slab out-of-bounds write in trace/trace_events_filter.c
An issue was discovered in the Linux kernel in the filter parsing code in kernel/trace/trace_events_filter.c. The code could be called with no filter, when it expected at least one. This allows attackers to cause a slab out-of-bounds write and so a denial of service via crafted perf_event_open and mmap system calls.
