CVE-2019-20096

Priority
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.
Ubuntu-Description
It was discovered that the Datagram Congestion Control Protocol (DCCP)
implementation in the Linux kernel did not properly deallocate memory
in certain error conditions. An attacker could possibly use this to
cause a denial of service (kernel memory exhaustion).
