Description

In the Linux kernel before 5.1, there is a memory leak in __feat_register_sp() in net/dccp/feat.c, which may cause denial of service, aka CID-1d3ff0950e2b. A flaw was found in the Linux kernel’s implementation of the Datagram Congestion Control Protocol (DCCP). A local attacker with access to the system can create DCCP sockets to cause a memory leak and repeat this operation to exhaust all memory and panic the system.
