CVE-2017-17854
kernel/bpf/verifier.c in the Linux kernel through 4.14.8 allows local users to cause a denial of service (integer overflow and memory corruption) or possibly have unspecified other impact by leveraging unrestricted integer values for pointer arithmetic.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.39%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
