CVE-2018-12714

kernel: slab out-of-bounds write in trace/trace_events_filter.c

Published Jun 24, 2018 CVSS 3.1 · 9.8 Critical EPSS 4.9% KEV · Not listed
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.
