ArchLinux: 201905-2: linux: arbitrary code execution
Summary
udp_gro_receive_segment in net/ipv4/udp_offload.c in the Linux kernel 5.x through 5.0.11 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.
Resolution
Upgrade to 5.0.12.arch2-1.
# pacman -Syu "linux>=5.0.12.arch2-1"
The problem has been fixed upstream in version 5.0.12.arch2.
