CVE-2019-17055

Published: 01 October 2019

base_sock_create in drivers/isdn/mISDN/socket.c in the AF_ISDN 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-b91ee4aa2a21.

From the Ubuntu security team

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

Priority

Medium

CVSS 3 base score: 3.3
