Description
A flaw was found in Linux kernel tipc. tipc_udp_addr2str() does not return a nonzero value when UDP media address is invalid, which can result in a buffer overflow in tipc_media_addr_printf().
Statement
This vulnerability exists in the kernel's TIPC networking code. This functionality is typically only used for low-latency interprocess communication between nodes in a cluster computer. Additionally, an attacker must be able to create a UDP connection with an invalid address. Since this vulnerability is only applicable to systems using TIPC and exploitation requires an attacker to already have significant privileges on the target system, Red Hat assesses this flaw as having Moderate impact.
