CVE-2018-12714
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.07%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
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.
