CVE-2018-21206
Certain NETGEAR devices are affected by a stack-based buffer overflow by an unauthenticated attacker.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.66%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
