CVE-2019-11683
Published: 02 May 2019
udp_gro_receive_segment in net/ipv4/udp_offload.c in the Linux kernel 5.x before 5.0.13 allows remote attackers to cause a denial of service (slab-out-of-bounds memory corruption) or possibly have unspecified other impact via UDP packets with a 0 payload, because of mishandling of padded packets, aka the "GRO packet of death" issue.
From the Ubuntu security team
It was discovered that the IPv4 generic receive offload (GRO) for UDP implementation in the Linux kernel did not properly handle padded packets. A remote attacker could use this to cause a denial of service (system crash).
