Description D'juan McDonald (domhnall) 2019-05-03 14:52:58 UTC

(https://nvd.nist.gov/vuln/detail/CVE-2019-11683):

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.

Patch: https://git.kernel.org/pub/scm/linux/kernel/git/davem/net.git/patch/?id=4dd2b82d5adfbe0b1587ccad7a8f76d826120f37
