CVE-2014-9428

Published: 2 January 2015

The batadv_frag_merge_packets function in net/batman-adv/fragmentation.c in the B.A.T.M.A.N. implementation in the Linux kernel through 3.18.1 uses an incorrect length field during a calculation of an amount of memory, which allows remote attackers to cause a denial of service (mesh-node system crash) via fragmented packets.

From the Ubuntu Security Team

A flaw was discovered in the fragment handling of the B.A.T.M.A.N. Advanced Meshing Protocol in the Linux kernel. A remote attacker could exploit this flaw to cause a denial of service (mesh-node system crash) via fragmented packets.
