kernel is vulnerable to denial of service (DoS). The vulnerability exists as a flaw was found in the Linux kernel’s networking subsystem. If the number of packets received exceeded the receiver’s buffer limit, they were queued in a backlog, consuming memory, instead of being discarded. A remote attacker could abuse this flaw to cause a denial of service (out-of-memory condition).
