CVE-2019-12984
A NULL pointer dereference vulnerability in the function nfc_genl_deactivate_target() in net/nfc/netlink.c in the Linux kernel before 5.1.13 can be triggered by a malicious user-mode program that omits certain NFC attributes, leading to denial of service.
Does this matter?
Lower severity and a low EPSS score (2.36%). Track it; it rarely justifies an emergency change on its own.
