kernel: net: DoS due to routing packets to too many different dsts/too fast
Published Apr 5, 2015

HIGHCVSS 2.0
EPSS 6.47%
Description
The IPv4 implementation in the Linux kernel before 3.18.8 does not properly consider the length of the Read-Copy Update (RCU) grace period for redirecting lookups in the absence of caching, which allows remote attackers to cause a denial of service (memory consumption or system crash) via a flood of packets.
