CVE-2019-11683 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. 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.. EPSS estimates a 7.07% chance of exploitation in the next 30 days.
