CVE-2019-17052

Published: 01 October 2019

ax25_create in net/ax25/af_ax25.c in the AF_AX25 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-0614e2b73768.

From the Ubuntu security team

Ori Nimron discovered that the AX25 network protocol implementation in the Linux kernel did not properly perform permissions checks. A local attacker could use this to create a raw socket.
