Vulnerability id: CVE-2017-15274
A flaw was discovered in the key management subsystem of the Linux kernel. It allowed to pass NULL payload with non-zero payload length as parameters to sys_add_key() and the KEYCTL_UPDATE operation of sys_keyctl(). A local unprivileged user could exploit this to cause a kernel crash (NULL pointer dereference).
