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.
Notes
| Author | Note |
|---|---|
| tyhicks | The receiving socket has to have the UDP_GRO socket option explicitly enabled with a call to setsockopt(2). UDP sockets are not vulnerable to this attack by default. |
