CVE-2017-15274
Published: 11 October 2017
security/keys/keyctl.c in the Linux kernel before 4.11.5 does not consider the case of a NULL payload in conjunction with a nonzero length value, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) via a crafted add_key or keyctl system call, a different vulnerability than CVE-2017-12192.
From the Ubuntu Security Team
It was discovered that the key management subsystem in the Linux kernel did not properly handle NULL payloads with non-zero length values. A local attacker could use this to cause a denial of service (system crash).
