CVE-2018-12714

An issue was discovered in the Linux kernel through 4.17.2.

An issue was discovered in the Linux kernel through 4.17.2. The filter parsing in kernel/trace/traceeventsfilter.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 perfeventopen and mmap system calls.
