CVE-2018-12714

Priority
Description
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.
