  "title": "Dhcpcd: dhcpcd infinite loop and out-of-bounds read via zero-length ipv6 nd option in router advertisement handling",
  "description": "A flaw was found in dhcpcd\u0027s IPv6 Neighbor Discovery Router Advertisement processing. A specially crafted IPv6 Router Advertisement containing a zero-length Neighbor Discovery option can bypass validation during packet storage and later be reparsed without adequate validation, causing the parser to enter a non-advancing loop. Successful exploitation may result in excessive CPU consumption, leading to a denial of service.",
