Note: Versions mentioned in the description apply only to the upstream kernel-rt-trace-devel package and not the kernel-rt-trace-devel package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

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.
