CVE-2019-17056
Published: 1 October 2019
llcp_sock_create in net/nfc/llcp_sock.c in the AF_NFC 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-3a359798b176.
From the Ubuntu Security Team
Ori Nimron discovered that the Near field Communication (NFC) network protocol implementation in the Linux kernel did not properly perform permissions checks. A local attacker could use this to create a raw socket.
