Multiple missing checks on headers length when using UDP Fragmentation
Offload (UFO) protocol while sending packets could lead to out-of-bounds
accesses. A local attacker with CAP_NET_RAW capability, or on a system
with unprivileged namespace enabled, could use this flaw to cause a
denial-of-service or execute arbitrary code.

a buffer overflow and to an infinite loop. A remote attacker could use
this flaw to cause a denial-of-service.
