Description Dhananjay Arunesh 2019-06-27 13:10:14 UTC 
A NULL pointer dereference vulnerability in the function nfc_genl_deactivate_target() in net/nfc/netlink.c in the Linux kernel can be triggered by a malicious user-mode program that omits certain NFC attributes, leading to denial of service.

At this time no Red Hat Products ship this code enabled in a build.
