CVE-2014-1874
The security_context_to_sid_core function in security/selinux/ss/services.c in the Linux kernel before 3.13.4 allows local users to cause a denial of service (system crash) by leveraging the CAP_MAC_ADMIN capability to set a zero-length security context.

Does this matter?
Lower severity and a low EPSS score (0.60%). Track it; it rarely justifies an emergency change on its own.
