CVE-2019-17054

Published: 1 October 2019

atalk_create in net/appletalk/ddp.c in the AF_APPLETALK network module in the Linux kernel through 5.3.2 does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka CID-6cc03e8aa36c.

From the Ubuntu security team

Ori Nimron discovered that the Appletalk network protocol implementation in the Linux kernel did not properly perform permissions checks. A local attacker could use this to create a raw socket.
